An interesting bug in n/troff regarding comments is that a comment following
a command must be preceeded by spaces and not tabs!  That is,

.xx	\" this comment preceeded by a tab, and may cause n/troff to blow up.
.xx     \" this comment is preceeded by 5 blanks, and will work ok.

The reason for this is obscure, but the bug was reported and will be fixed
(hopefully) in a future release.
