Call grep-compute-defaults unconditionally.
(grep-expand-keywords): New defconst.
(grep-expand-template): Rename from grep-expand-command-macros.
Simplify via grep-expand-keywords. Look at case-fold-search instead

`font-lock-keyword-face'.
(grep-mode-font-lock-keywords): Use `compilation-info-text-face'
and `compilation-warning-text-face' instead of `font-lock-keyword-face'.
Use `compilation-error-text-face' instead of `grep-error-face'.
matching line numbers, column numbers and their ranges with regexp
matching only line numbers.
(grep-context-face): New face variable.
(grep-mode-font-lock-keywords): Use it.
(grep-mode-font-lock-keywords, grep-process-setup):
Use default GNU grep match color "01;31m" instead of "01;41m".
(grep-regexp-alist, grep-mode-font-lock-keywords):
Use `\\[[0-9]*m' instead of `\\[00m'.
(grep-regexp-alist): Move `\\(?:\033\\[K\\)?' from sgr_end to
sgr_start where its handling is more important. Use the real
length of sgr_start instead of constant 8.
(grep-mode-font-lock-keywords): Don't delete `\\(?:\033\\[K\\)?'
specially. Delete all remaining escape sequences.
(grep-process-setup): Set "GREP_COLORS" for GNU grep 2.5.1-cvs.
(grep-regexp-alist): Make hyperlink only for binary file name
instead of the whole line.
(grep-mode-map): Bind `backtab' to `compilation-previous-file'.
(grep-mode): Add autoload.
end of first regexp to limit the match to the position between
line number and source line with same separator character as used
between file name and line number. In the second regexp limit
mouse-face area to file name and line number by adding new group
for them and referring it in HYPERLINK arg.
(grep-regexp-alist, grep-mode-font-lock-keywords): Use shy group.
(grep-mode): Set font-lock-lines-before to 0 to not refontify the
previous line where grep markers may be already removed.
`t' to `auto-detect', and type from `boolean' to `choice'.
(grep-compute-defaults): Set `grep-highlight-matches' to `t'
if grep option `--color' is available, or to `nil' otherwise.
(grep-use-null-device): Remove redundant type `boolean' (`choice'
is already defined).
(grep-program, find-program, grep-find-use-xargs, grep-history)
(grep-find-history, grep-tag-default, grep-find-command)
(grep-regexp-alist, grep-process-setup, grep-compute-defaults):
Add autoload cookies, for unbundled packages that load `compile'
and expect all grep-related symbols to become defined.
