Here's what I committed instead, after first cleaning up CVS to not
include generated files. I verified that it tickles the bug if your
November patch is reverted (the first quote character is never pushed
back, so the multi-char push_string_init requires a changequote of 3 or
more characters). I added your name to THANKS (it was inadvertantly left
out from your November patch), but am not including that patch here since
it includes random email addresses.
