That solves that particular problem but the '$' caused other problems 
for me during the semiautomated process of updating the copyright.

POSIX excludes '$' from the list of characters in portable filenames 
<https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap03.html#tag_03_282> 
and we'll avoid these hassles by sticking to the POSIX character set.

I can of course redo the scripts to handle '$' in filenames on GNU 
platforms. I could even hack them to handle other characters, too, like 
newline etc. in filenames. And others who deal with Emacs sources could 
do likewise. But that'd be a hassle and we all have better things to do.
