Subject: git rev-parse -q --verify $SHA doesn't always quiet errors
Message-ID: <4A1CAE91-E31C-46B5-A614-9634D8FC1FB1@sb.org>

The -q flag to git rev-parse --verify is supposed to quiet all errors.
However it doesn't appear to quiet the "short SHA1 is ambiguous" error.

% cd Dev/git
% git rev-parse -q --verify e51d
error: short SHA1 e51d is ambiguous.

I took a quick look, and the error is being emitted deep within
sha1_name.c, far outside of any access to the -q flag. I'm not sure how
to go about fixing this. Does anyone have any ideas?

Alternatively, is there a better way to tell if a given string can
resolve into a full sha1 besides

  git rev-parse -q --verify "$word" 2>/dev/null
