Dear James,

Thank you for the report. The last version released was 5.2, but there
was a similar issue in the most recent version anyway. I've committed
a change to not use a fixed-length buffer. I don't know why anybody
would be asking for a manpage with 1000's of bytes in its name, but I
guess it is useful to be able to ignore these things when looking for
other flaws.

Thanks
Gavin
