Subject: Do not misidentify "git merge foo HEAD" as an old-style invocation
X-Git-Tag: v1.6.6-rc1~2^2~2
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=76bf488e61b8a87191a1779b79820545e64ef275;p=git-core%2Fgit.git

Do not misidentify "git merge foo HEAD" as an old-style invocation

This was misinterpreted as an ancient style "git merge <message> HEAD
<commit> <commit>..." that merges one (or more) <commit> into the current
branch and record the resulting commit with the given message.  Then a
later sanity check found that there is no <commit> specified and gave
a usage message.
