[PATCH v4 0/3]

Sorry for the idiotic wrapping problems in my last email.

Previously, I was trying to keep from changing any of the important stuff, like git-rev-list, but I should know better than cut-and-pasting code.

As requested, I've broken the change into a multiple of patches. First moving read_revisions_from_stdin to revision.c, next modifying git-bundle to handle --stdin, and finally a patch adding my old git-basis to contrib.

I think I've corrected all of the style issues you pointed out, and I've also tried to craft more informative commit messages.
