there is inconsistency between the grep RE letter assignments,
ksh ~(...) parsing, and libast regcomp() ~(...) parsing
(ksh must dig into ~(...) to change ()&| lexing on the fly)
for now use A (augmented) instead of X for extended+conjunction+negation
I'll post a beta next week with these assignments
A|X xgrep extended+conjunction+negation
B|G grep basic
E egrep extended
F|L fgrep literal
K ksh grouping+alternation+conjunction+negation
P pgrep pcre compatibility -- close but not complete (may never
be)
S sh basic shell patterns
via changes to
src/lib/libast/regex/regcomp.c
src/cmd/ksh93/sh/macro.c
