The comment is now in a comment inset. This change is extended to
all versions of beamer.lyx.
Change tracking is not used because it only affects a comment
(consistent with aa81ae7e).
This change is made according to updated conversation at:
https://www.mail-archive.com/search?l=mid&q=nruubc%24uu0%241%40blaine.gmane.org
Also MacOSX ReadMe files. Note that a few lib/doc files are
also "updated" because trailing spaces are removed, but their file
formats are the same because they were recently updated at 83672113.
I did "git checkout LFUNs.lyx" because this file is generated
automatically and has a special header.
