Yeah, it is simply a bad taste to use helper in builtin-A from builtin-B.
More library-ish files such as revision.c are better home for utility
functions to be shared between builtins and commands.

Here is what I queued.

By the way did you compile test your fix before sending?

Move read_revisions_from_stdin from builtin-rev-list.c to revision.c

Reading rev-list parameters from the command line can be reused by
commands other than rev-list.  Move this function to more "library-ish"
place to promote code reuse.
