A renderer that speaks the protocol emits nothing unless it is asked to,
so that its output stays plain wherever it is used outside lazygit. The
variable names the versions we understand.
git is one of the renderers we ask. It has no pager to spawn, and so no
terminal to spawn one in, but it still renders the diff itself — for the
word-diff formats, whose markup nothing else could resolve — so the
request has to be made before we decide a pty isn't needed.

Changing the screen mode renders the main view again, and so does
anything else that changes its size along with what it shows. With git's
own diff, that render laid a commit's diffstat out to the width the view
had before. The graph then wrapped onto rows of its own in a view that
got narrower, and stopped short in one that got wider.
A diff renderer's render is created after the layout pass, since only
the layout settles the view's size, and takes its width there. git's own
diff took its width straight away instead, when the render was asked
for. Create its task after the layout as well.

Pressing + in the commits panel moves to half-screen mode and renders
the commit's diff again in the narrower main view. With git's own diff,
the diffstat graph comes out as wide as the view was before, and wraps
onto rows of its own.
ContainsViewLines asserts on the rows the view draws, after wrapping.
The existing line assertions see the lines of the content and can't tell
a wrapped line from one that fits.

ConPTY doesn't carry a diff renderer's output to us as the renderer
wrote it. It parses the output into a screen buffer and re-encodes that
for the terminal side, and a sequence it can't represent there goes out
the moment it is parsed, separately from the text around it. The OSC
1717 records a renderer states its diff lines in therefore arrive
detached from the rows they describe, and the identity layer attributes
rows to the wrong diff line or to none.
Feed the renderer through a pipe there instead, so that its bytes reach
us unaltered. A stdin filter becomes a command of our own, since git
only invokes the one named by GIT_PAGER when it talks to a terminal; an
external diff renderer is git's own business either way and needs
nothing but the pipe.
Unix keeps the pty. A renderer reads the width to lay out to off it, so
taking it away would leave every configuration that doesn't name a
width rendering at whatever the renderer falls back to, and diff
renderers have worked on Unix far too long for that.
LAZYGIT_RENDER_WITHOUT_PTY asks for the piped path anyway, which is how
the integration tests cover it on a platform where they run at all.

Tell a command that renders into a view how wide that view is, through
COLUMNS. git reads it in preference to the size of the terminal it is
talking to, so the diffstat now fills the view whether or not the render
has a terminal to offer.
A diff renderer that can't ask a terminal gets the width from it too;
difftastic, diff-so-fancy and delta all support COLUMNS, so we can stop
running git in a PTY and these will still work.

git scales the graph of a diffstat to the width of the terminal it is
talking to. A render that talks to no terminal tells it no width, so the
stat comes out narrower than the view it is shown in, wasting most of a
wide one.

For a long time lazygit has used the term "custom pager" to refer to
what's really a "diff renderer". A pager is a program that allows you to
view output page by page (hence the name), e.g. less; lazygit's custom
diff renderers are not pagers. It used the term only because the feature
is implemented using git's GIT_PAGER env var, but that's an
implementation detail.
Rename the 'git.pagers' config to 'git.diffRenderers', and restructure
its elements while we're at it to make things clearer:
- Add a 'type' field to explicitly specify which type of diff renderer
it is (the two fundamentally different ones are 'stdinFilter' and
'extDiff').
- Add a third type, 'rawGit', which has an 'args' field that makes it
easy to use 'git --color-words' as a custom renderer
- Unify the old 'pager' and 'externalDiffCommand' fields to a single
'command' field for both types
Existing config files are migrated automatically.
With more than a couple of pagers, having to cycle forward through all
of them to reach the previous one (or to back out of an accidental press
of `|`) is tedious. Add a second binding that cycles backward.

Change the tests so that they run in a linked worktree; this uncovers the bug
that copying a file's absolute path uses the main repo path rather than the
worktree's path.
This is useful for copying the entire content of the selected file as it was at
the selected commit.
We only add it to the commit files panel; it is not needed in the files panel,
because there you can simply press "e" to edit the file.
This is very similar to the same menu in the Files panel, except that it works
on whatever diff is currently shown in the main view, including range diffs
either in diffing mode (shift-W), or from a range selection of commits.
We have not been good at consistent casing so far. Now we use 'Sentence case' everywhere. EVERYWHERE.
Also Removing 'Lc' prefix from i18n field names: the 'Lc' stood for lowercase but now that everything
is in 'Sentence case' there's no need for the distinction.
I've got a couple lower case things I've kept: namely, things that show up in parentheses.
By constructing an arg vector manually, we no longer need to quote arguments
Mandate that args must be passed when building a command
Now you need to provide an args array when building a command.
There are a handful of places where we need to deal with a string,
such as with user-defined custom commands, and for those we now require
that at the callsite they use str.ToArgv to do that. I don't want
to provide a method out of the box for it because I want to discourage its
use.
For some reason we were invoking a command through a shell when amending a
commit, and I don't believe we needed to do that as there was nothing user-
supplied about the command. So I've switched to using a regular command out-
side the shell there
