- 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
