Well, according to ParseWords's documentation: https://perldoc.perl.org/Text/ParseWords.html parse_line should take a line ($line, in our case), a delimeter (\s+, in our case), and split the line into tokens respecting the delimeters. It is obviously not working the way it should when there is a backslash in the middle of the line, which is strange. I'm not saying there is a bug in the implementation, but, in this specific scenario, the documentation doesn't reflect what really happens (that is, the function doesn't return the expected tokens). >> What do you think? > > Would Text::Balanced help extract the quoted strings, and work from there? I don't know. As I said, Perl is not my specialty. But the problem here is not just removing the backslash; the real problem is that the title of the manpage (the first element in the .TH header) contains an \FB in the beginning, which seems to be wrong (there is no \fR in the line, and man doesn't render the title in bold, ignoring the \fB). Not mentioning the backslash at the end of the title, which (erroneously) escapes the double quote. I don't have the time right now to play a bit with Text::Balanced and see what comes out of it, so if you're not satisfied with the solution I proposed, my other suggestion would be to revert the original patch (and reintroduce the bug I fixed with it, of course) until we can figure out how to tackle this issue.
