Why these dot chars in scripts/checkpatch.pl?

Andy,

Perhaps I'm loosing my magic regex pixie dust, but the dot '.' char
in the pattern "/^.#" in the following lines looks wrong to me, as if
one were trying to match pre-processor directives that were set in by
one character:

The command:

	grep '^[^#].*\/\^\.#' scripts/checkpatch.pl

displays:

        if ($res =~ /^.#\s*include\s+\<(.*)\>/) {
        } elsif ($res =~ /^.#\s*(?:error|warning)\s+(.*)\b/) {
                if ($line =~ /(.*)\b((?:if|while|for|switch)\s*\(|do\b|else\b)/ && $line !~ /^.#/) {
                if ($line =~ /^.#\s*if\s+0\b/) {
                if ($line =~ /^.#\s*(ifdef|ifndef|elif)\s\s+/) {
                    $line !~ /^.#\s*if\b.*\bNR_CPUS\b/ &&
                    $line !~ /^.#\s*define\b.*\bNR_CPUS\b/ &&
