Merge pull request #2551 from stefanhaller/fix-initial-context-activation

We now refresh the staging panel when doing an unscoped refresh, so that if we commit from the staging panel we escape
back to the files panel if need be. But that causes flickering when doing an unscoped refresh from other contexts,
because the refreshStagingPanel function assumes that the staging panel has focus. So we're adding a guard at the top
of that function to early exit if we don't have focus.

 ### Configuring File Editing
 
-Lazygit will edit a file with the first set editor in the following:
+There are two commands for opening files, `o` for "open" and `e` for "edit". `o`
+acts as if the file was double-clicked in the Finder/Explorer, so it also works
+for non-text files, whereas `e` opens the file in an editor. `e` can also jump
+to the right line in the file if you invoke it from the staging panel, for
+example.
 
-1. config.yaml
+To tell lazygit which editor to use for the `e` command, the easiest way to do
+that is to provide an editPreset config, e.g.
 
 ```yaml
 os:
-  editCommand: 'vim' # as an example
+  editPreset: 'vscode'
 ```
 
-2. \$(git config core.editor)
-3. \$GIT_EDITOR
-4. \$VISUAL
-5. \$EDITOR
-6. \$(which vi)
+Supported presets are `vim`, `emacs`, `nano`, `vscode`, `sublime`, `bbedit`, and
+`xcode`. In many cases lazygit will be able to guess the right preset from your
+$(git config core.editor), or an environment variable such as $VISUAL or $EDITOR.
 
-Lazygit will log an error if none of these options are set.
-
-You can specify the current line number when you're in the patch explorer.
+If for some reason you are not happy with the default commands from a preset, or
+there simply is no preset for your editor, you can customize the commands by
+setting the `edit`, `editAtLine`, and `editAtLineAndWait` options, e.g.:
 
 ```yaml
 os:
-  editCommand: 'vim'
-  editCommandTemplate: '{{editor}} +{{line}} -- {{filename}}'
+  edit: 'myeditor {{filename}}'
+  editAtLine: 'myeditor --line={{line}} {{filename}}'
+  editAtLineAndWait: 'myeditor --block --line={{line}} {{filename}}'
+  editInTerminal: true
 ```
 
-or
+The `editInTerminal` option is used to decide whether lazygit needs to suspend
+itself to the background before calling the editor.
 
-```yaml
-os:
-  editCommand: 'code'
-  editCommandTemplate: '{{editor}} --goto -- {{filename}}:{{line}}'
-```
-
-`{{editor}}` in `editCommandTemplate` is replaced with the value of `editCommand`.
+Contributions of new editor presets are welcome; see the `getPreset` function in
+[`editor_presets.go`](https://github.com/jesseduffield/lazygit/blob/master/pkg/config/editor_presets.go).
