- 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)

- Fix cursor position being saved when escaping out of nanogetstr with keys like ^Y and ^V.  New arg resetpos to nanogetstr(), added static int resetpos in statusq() (bug found by DLR)
