[PATCH 0/2] specify commit by negative pattern

add support for negative pattern matching in @^{/<pattern>} style
revision specifiers. So now you can find the first commit whose message
doesn't match a pattern, complementing the existing positive matching.
e.g.:

    $ git rebase -i @^{/!^WIP}

My use-case is in having a "work, work, work, rebase, push"-style
workflow, which generates a lot of "WIP foo" commits. While rebasing is
usually handled via "git rebase -i origin/master", occasionally I will
already have several "good, but not yet ready to push" commits hanging
around while I finish work on related commits. In these situations, the
ability to quickly "git diff @^{/!^WIP}" to get an overview of all
changes "since the last one I was happy with", can be useful.

Reading through the history of this type of revision specifier, it feels
like a negative match was always thought of as potentially useful
someday, but didn't fit well with the original patch's limitations
(namely: always searching across all refs).
