Hmm, for AS_BOX, I changed things to avoid AS_LITERAL_IF altogether,
and just hard-coded the check for $, \, and ` (the three things that are
not safe for an unquoted here-doc).  I could probably do the same
for AC_INIT on the version string, but I'm out of time this morning for
attempting that.  Maybe tonight...

(And I finally figured out a way to get my normal email client to
work remotely, instead of suffering through the web-mail interface
that was breaking threading).
