What's wrong with XXX'ed comments?  I could create an issue for this, but it would seem weird to be creating a new issue for something that's not part of master yet.  What I had in mind, is that it would be nice to have the `UuencodeAnalyzer` et al to refuse a file if it doesn't actually match after all.  I guess I could copy the code from the `plain` analyser to handle binary files (which just provides a download link, or, in the future, perhaps could do something more interesting, like `hexdump -C`), but I think it might be a better idea to simply pass the control back to the matching logic in such cases.  (Similar functionality might also be interesting for my `mdoc` analyser, too, BTW, as per Issue #33 and the idea of having two separate analysers for `man` and `mdoc`.)
