We move the selection down by the number of commits that were reverted (to keep
the same commits selected). However, this only happens after refreshing, which
has rendered the main view with the wrong commit, so we need to render it again
after moving the selection.
There are many other callers of MoveSelection in LocalCommitsController, but all
of them happen before the refresh. Revert is special because it needs to move
the selection after refreshing, e.g. when reverting the only commit of a branch.
CheckMergeOrRebase calls Refresh already. However, it does an async refresh by
default, so we must turn this into a sync refresh so that moving the selection
down by one works even for the very first commit in history. Also, we must add
an explicit call to FocusLine so that the view selection is in sync with the
model selection; previously this was taken care of by the PostRefreshUpdate call
that happens as part of a refresh.
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
