Subject: Update callers of check_ref_format()
X-Git-Tag: v1.5.4-rc3~59
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=257f3020f69f3222cdefc1d84b148fb35b2c4f5b;p=git.git

Update callers of check_ref_format()

This updates send-pack and fast-import to use symbolic constants
for checking the return values from check_ref_format(), and also
futureproof the logic in lock_any_ref_for_update() to explicitly
name the case that is usually considered an error but is Ok for
this particular use.
