- Fix nano crashing when searching/replacing an invalid
regex (try "^*"). Changed regexp_init() to return
1 or 0 based on regcomp()'s return value and search_init
to exit with an error message (sorry Jordi!)
to exit with an error message (sorry Jordi!). Added
another check when using last_search instead of answer.
- Move regcomp into rcfile.c rather than each display refresh
of winio.c. New function rcfile.c:nregcomp().
This fixes much of nano's resource hogging behavior
