Harald Nordgren c07039ebc4 checkout -m: autostash when switching branches
When switching branches with "git checkout -m", the attempted merge
of local modifications may cause conflicts with the changes made on
the other branch, which the user may not want to (or may not be able
to) resolve right now.  Because there is no easy way to recover from
this situation, we discouraged users from using "checkout -m" unless
they are certain their changes are trivial and within their ability
to resolve conflicts.

Teach the -m flow to create a temporary stash before switching and
reapply it after.  On success, the stash is silently applied and
the list of locally modified paths is shown, same as a successful
"git checkout" without "-m".

If reapplying causes conflicts, the stash is kept and the user is
told they can resolve and run "git stash drop", or run "git reset
--hard" and later "git stash pop" to recover their changes.
