The cause of the unwanted escape sequences in the text output is that
linuxdoc uses groff for text output. groff uses grotty as a post
processor and grotty by default puts the escape seqences there per the
man page for grotty. A fix is to pass the -c option to grotty to
disable this. But how to do this when groff is called? I can't find
out how to do this from the man page or the info page for groff. If I
substitute nroff -c for groff, the problem is fixed but using nroff
may break something else. nroff uses the option -T... while groff uses
-T ... (the difference is a space after -T). So I had to change this
too when I substituted nroff. There are likely some other
differences. One could also try using troff in a pipeline with grotty
to enable the appropriate options to be given to grotty.
I really don't know Perl so I was lucky to discover possible solutions.
