[tor-commits] [tor/release-0.4.6] Stop using the "x$FOO" idiom in git-resquash.sh

[nickm at torproject.org]

commit 8b6e919086ad6dde681516fe52d744afa3ffcc89
Author: Nick Mathewson <nickm at torproject.org>
Date:   Fri May 28 08:02:08 2021 -0400

    Stop using the "x$FOO" idiom in git-resquash.sh
    
    The new version of shellcheck says that that this idiom is
    unnecessary, and its presence here is making the shellcheck tests
    fail.
    
    No changes file needed, since this is not user-facing code.
