Everyone, please stop making my life more difficult

[Eric S. Raymond]

While running my latest repository conversion, I found this comment

    revno: 116811.1.662
    fixes bug: http://debbugs.gnu.org/18384
    committer: Eli Zaretskii <address@hidden>
    branch nick: emacs-24
    timestamp: Tue 2014-09-02 18:16:42 +0300
    message:
      Fix bug #18384 with incorrect reporting of row number by posn-col-row.
      
       lisp/subr.el (posn-col-row): Revert the change from commit
       r99634.2.576 address@hidden, which
       was inadvertently merged from emacs-23 release branch in r102428
       address@hidden, and
       introduced an off-by-one error in the reported row when there is a
       header line.
      
       src/dispnew.c (buffer_posn_from_coords): Fix an off-by-one error in
       the reported row in the case of a window with a header line, by
       improving on the fix committed in r106022
       address@hidden

There are two things about this comment that make my life
unnecessarily more difficult.

1) People are continuing to embed bzr revision numbers like
   r99634.2.576 and r102428 in comments.  Do not do this.  
   They're soon going to cease being meaningful, and every time
   I have to run another conversion to clean these out it costs
   me eight to ten hours.

2) "address@hidden" Um.  What the *hell*?
   This is not the time to be inventing some random new magic-cookie
   commit reference format that my tools don't know how to recognize.
   That should have been 2010-11-13T21:07:address@hidden (I think).

Please stop this nonsense.  Now I'm going to have to write a new comment
scanner to find these monster turds, and it's going to take me hours
of work to make sure I've cleaned them all out.

The correct format for a commit reference that will remain
intelligible across every VCS, forever, is this:

<RFC3339-date>!<email-address>

Example: 2010-11-13T21:07:address@hidden

That is what everyone should be using, now and in the future, to avoid
causing unnecessary problems for this repository conversion and any 
we may have to do in the future.
