[PATCH 1/2] legacy stash: fix "rudimentary backport of -q"

From: Johannes Schindelin <johannes.schindelin@gmx.de>

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.
