Subject: make checkout-index '-a' flag saner.
X-Git-Tag: v0.99.8e~1^2~1
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=a65a686f4967ecba0759289d0e918f652980e8a2;p=git.git

make checkout-index '-a' flag saner.

The original semantics of pretending as if all files were
specified where '-a' appeared and using only the flags given so
far was too confusing.
