Make 'got rm' keep empty directories which are not explicitly listed for deletion. Deleting such directories is problematic in several use cases. Avoids deleting the current working directory when the user runs "got rm *" (pointed out by Mikhail), and avoids deletion of an empty directory "foo/" after 'got rm foo/a foo/b' (pointed out by op@). ok jamsek, op

Draw reference labels and log message as separate strings. The previous code contained calculations mixing variables which represent an amount of wide characters in a string vs the display width of the string. We can avoid such nonsense by keeping the strings separate, though we have to be a bit careful about keeping horizontal scrolling intact. Also fix a bug where we failed to account for reference labels while setting view->maxx which made the $ key not scroll far enough. ok op@

it's not printf-like so %s don't make sense. Tweak the order of the arguments to obtain the intended output.

patch from Josiah Frentsos, thanks!

Backup references clutter the log view too much now that we display labels next to commit messages. They were accidentally added to the log and diffs view by me, via build_refs_str(), when support for listing backup references was added to the ref view.

When the terminal becomes smaller horizontally we did not properly account for remaining columns and the log message of a commit could overflow into the next line, garbling the display.

No behaviour change as the end result of the rewritten checks should be the same as before. We are just doing less work where possible. Patch by James Cook
