Re: [PATCH] t3420-rebase-autostash: don't try to grep non-existing files

> Several tests in 't3420-rebase-autostash.sh' start various rebase
> processes that are expected to fail because of merge conflicts.  The
> tests [1] checking that 'git rebase --quit' and autostash work
> together as expected after such a failure then run '! grep ...' to
