Prefer grep -E/-F to egrep/fgrep
POSIX marked egrep and fgrep as legacy apps in SUSv2 (1997) and
withdrew them in SUSv3 (2001), and these days grep -E and grep -F
are probably more portable.
* lib-src/etags.c (main):
* lisp/eshell/em-unix.el (eshell-grep, eshell/egrep)
(eshell/fgrep):
* lisp/cedet/semantic/symref.el (semantic-symref-find-text):
* lisp/eshell/esh-var.el (eshell-apply-indices):
* lisp/progmodes/ada-xref.el (ada-xref-search-with-egrep)
(ada-find-in-src-path):
* lisp/textmodes/ispell.el (ispell-grep-command):
(ispell-lookup-words):
Use or document grep -E and grep -F instead of egrep and fgrep.
* lisp/textmodes/ispell.el (ispell-grep-options):
Use -Ei on all platforms, not just MS-Windows.
