    """search revision history for a pattern in specified files

    Search revision history for a regular expression in the specified
    files or the entire project.

    By default, grep prints the most recent revision number for each
    file in which it finds a match. To get it to print every revision
    that contains a change in match status ("-" for a match that becomes
    a non-match, or "+" for a non-match that becomes a match), use the
    --diff flag.

    PATTERN can be any Python (roughly Perl-compatible) regular
    expression.

    If no FILEs are specified (and -f/--follow isn't set), all files in

        ui.warn(_("grep: invalid match pattern: %s\n") % pycompat.bytestr(inst))
        return 1
    sep, eol = ':', '\n'

        sep = eol = '\0'
