We'll make some changes to how the display strings are rendered, so it helps to
have this code only once. This also fixes the problem that contexts using
refreshViewportOnChange weren't able to use column alignments so far. We didn't
need this yet, but it's just nice if everything works. :)
This spares me effort when it comes to making release notes.
Yes, sometimes it may be easier to start a message without an imperative e.g. 'When X happens, do Y'
but I don't want to overwhelm the contributor with details.
When editing a commit, the index of the current commit can change; for example,
when merge commits are involved, or when working with stacked branches where
"update-ref" commands may be added above the selected commit.
Reselect the current commit after pressing "e"; this requires doing the refresh
blocking on the main thread. (Another option that I considered was to use a
SYNC refresh, and then select the new line with an OnUIThread inside the Then
function. This also works, but results in a very visible lag.)
Only do this when an onSwitchToEditor function is actually provided. For the
"Move patch into new commit" command we don't, because it isn't totally
straightforward in that case.
This is useful for when you begin to type the message in lazygit's commit panel,
and then realize that you'd rather use your editor's more powerful editing
capabilities. Pressing <c-o> will take you right there.
When navigating in the commits view to a line that is out of view (e.g. by
pressing , or . to scroll by page, or < or > to scroll to the top or bottom),
the commit graph was not correctly highlighted. Fix this by rerendering the
viewport in this case.
