When this developer backported support for `--quiet` to the scripted
version of `git stash` in 80590055ea (stash: optionally use the scripted
version again, 2018-12-20), it looked like a sane choice to use `eval`
to execute the command line passed in via the parameter list of
`maybe_quiet`.

However, that is not what we should have done, as that command-line was
already in the correct shape.

This can be seen very clearly when passing arguments with special
characters, like

	git stash -- ':(glob)**/*.txt'

Since this is exactly what we want to test in the next commit (where we
fix this very incantation with the built-in stash), let's fix the legacy
scripted version of `git stash` first.
