Remove space after rebase todo

This is very old; I can only guess that this was added at a time where today's
list column handling wasn't in place yet, so the space was needed to separate
columns. This now causes a gap of two spaces between the rebase todo column and
the author column, which I'm sure wasn't intended. Funny that I never noticed.
