PATCH: completion fixes

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

There was a little memory freeing problem (with the list of free cline 
structs, if anyone knows what I'm talking about...). Also, in
addmatches() (a.k.a. almost compadd) the suffix-calculation could fail 
when used without matching.

Bye
 Sven
