(In reply to Jakub Jelinek from comment #2)

Yes, the code isn't perfect.  I think one bug is what you already pointed out
in the -Wrestrict code (bug 84095 comment #1) and that I recently submitted a
fix for.  There may be others.  I just filed bug 84395 for one issue.  I'll see
what other test cases I can come up with and open bugs for the problems I find.

The reference to '\0' in the comment describes the ideal goal I had in mind. 
It might be worth tightening things up to look for a literal zero.  I raised
bug 84396 for this.
