PATCH: tricky.c bug fix(es)

[Sven Wischnowsky <wischnow@informatik.hu-berlin.de>]

With in-word completion and suffixes that caused the code to reduce it 
to an empty common suffix this could lead to a SEGV.
And with the matching stuff we have now and in-word completion, we
should do the fignore-test in addmatch() even if there is a suffix.

Bye
 Sven
