Subject: Fix git-rev-parse over-eager errors
X-Git-Tag: v1.2.0~63
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=9523a4c2fcd7bbccbbddb998eef891ae83cf91a3;p=git.git

Fix git-rev-parse over-eager errors

Using "--verify" together with "--no-flags" makes perfect sense, but
git-rev-parse would complain about it when it saw a flag, even though it
would never actually use/output that flag.

This fixes it.
