* add a man page describing editrc
* fix bugs in el_parse():
* didn't execute command when program name matched (test reversed)
* was checking against empty string instead of program name
* after checks, command to run also pointed to empty string
[christos - the author of libedit - ok-ed the man pages in general (which I
wrote from scratch by RTFS) as well as the bugfix]
is defined, V8 regular expresion functions are used if REGEXP is defined,
and BSD regular expression functions are used if neither are defined.
And defined REGEX in sys.h so that programs using libedit don't have
to link with libcompat.
