[PATCH v5]

Apparently I'm dumber than I thought.  Here's what they look like without 
random and unnecessary mode changes.  The patch to add git-basis under contrib 
is not affected.

The real reason read_revisions_from_stdin moved to revision.c is because I was 
asked to do it that way.  If my commit message doesn't accurately describe the 
reason for the change, go ahead and edit the message, or let me know what the 
real reason is so I can provide a better message.
