[PATCH] Teach git-bundle to read revision arguments from stdin like

[Adam Brewster <adambrewster@xxxxxxxxx>]

This patch allows the caller to feed the revision parameters to
git-bundle from its standard input.  This way, a script do not have to
worry about limitation of the length of command line.

Documentation/git-bundle.txt says that git-bundle takes arguments
acceptable to git-rev-list.  Obviously some arguments that git-rev-list
handles don't make sense for git-bundle (e.g. --bisect) but --stdin is
pretty reasonable.
