runewidth.StringWidth is an expensive call, even if the input string is pure
ASCII. Improve this by providing a wrapper that short-circuits the call to len
if the input is ASCII.
Benchmark results show that for non-ASCII strings it makes no noticable
difference, but for ASCII strings it provides a more than 200x speedup.

Several custom patch commands on parts of an added file would fail with the
confusing error message "error: new file XXX depends on old contents". These
were dropping the custom patch from the original commit, moving the patch to a
new commit, moving it to a later commit, or moving it to the index.
We fix this by converting the patch header from an added file to a diff against
an empty file. We do this not just for the purpose of applying the patch, but
also for rendering it and copying it to the clip board. I'm not sure it matters
much in these cases, but it does feel more correct for a filtered patch to be
presented this way.
We're going to add another argument in the next commit, and that's getting a bit
much, especially when most of the arguments are bool and you only see true and
false at the call sites without knowing what they mean.
If exactly one candidate from inside the current branch is found, we return that
one even if there are also hunks belonging to master commits; we disregard those
in this case.
Copy the slice into a variable and use that throughout the whole operation; this
makes us a little more robust against the model refreshing concurrently.
Put it into the individual menu items instead.
Again, this is necessary because we are going to add another entry to the menu
that is independent of the selected branch.
Instead, disable the individual entries in the menu.
This is necessary because we are going to add another entry to the menu that is
independent of the selected branch.
We aren't using them, yet, except for deciding whether to show the warning about
hunks with only added lines.
Add a bit of test coverage for parseDiff while we're at it.
When branches are sorted by recency we have this logic that first loads the
branches so that they can be rendered quickly; in parallel, it starts loading
the reflog in the background, and when that's done, it loads the branches again
so that they get their recency values. This means that branches are loaded twice
at startup.
We don't need this logic when branches are not sorted by recency, so we can
simply load branches and reflog in parallel like everything else.
This shouldn't change any user observable behavior, it just avoids doing
unnecessary work at startup.
For tooltips that are just one or two characters longer than the available
width, the last word would be cut off. On my screen this happened for the
tooltip for the fixup command.
For custom commands it is useful to select an earlier command and have it copied
to the prompt for further editing. This can be done by hitting 'e' now.
For other types of suggestion panels we don't enable this behavior, as you can't
create arbitrary new items there that don't already exist as a suggestion.
In the custom commands panel you can now tab to the suggestions and hit 'd' to
delete items from there. Useful if you mistyped a command and don't want it to
appear in your history any more.
This lets us get rid of a few more calls to Error(), and it simplifies things
for clients of OnWorker: they can simply return an error from their callback
like we do everywhere else.
When exiting filtering mode, we currently keep the selection index the same in
the commits panel. This doesn't make sense at all, since the index in the
filtered view has no relation to the index in the unfiltered view.
I often use filtering mode (either by path or by author) to find a given commit
faster than I would otherwise be able to. When exiting filtering mode, it's
useful to keep the same commit selected, so that I can look at the surrounding
commits, see which branch it was a part of, etc. So reselect the commit again
after exiting filtering mode.
Sometimes this is not possible, most likely when the commit is so long ago that
it's outside of the initial 300 range. In that case, at least select the commit
again that was selected before I entered filtering; this is still better than
arbitrarily keeping the same selection index.
