Re: CVS: cvs.openbsd.org: src [shlib.c change]

Problem is that might_take_it is seriously confused about what it's 
trying to record. It's used
- to check whether a library fits,
- to check whether one library was found.

Fortunately, the first goal can be reached by simple uses of continue, without
any extra variables... I've also decided to rename it to found_match to avoid
further confusion.

Please try this. This should give us the semantics we are looking for.
