Sounds good to me (although I've got not much a vote here;))

Whether '#' is a comment marker boils down to semantics; it is 
definitely treated specially by Autoconf. This source snippet below, for 
example,

m4_define([my_hello], [HELLO WORLD!])
echo "my_hello and #my_hello"

will expand to

echo "HELLO WORLD! and #my_hello"

i.e. text following character '#' is not expanded by Autoconf, but 
copied verbatim.

Thanks,
Peter
