[Groff] Minor soelim patch

[Jörgen Grahn]

Here's another tiny bug fix against latest CVS. 

When soelim wrote error messages about being unable to open files, the
reported file name tended to have garbage characters appended to it.
Please apply.

('const char * string::contents() const' is devious. Wouldn't surprise me if
it is used incorrectly elsewhere, but I haven't checked in detail.)

BR,
