Avoid spawning a shell pipeline doing cat, grep, sed, and do it all
inside perl. The <*.c> globbing construct works at least as far back
as 5.8.9
Note that this is not just an optimization; the sed command
in the pipeline was unterminated, due to lack of escape on the
end-of-line (\$) in the regex, resulting in this:
$ perl ../linux-2.6/scripts/export_report.pl > /dev/null
sed: -e expression #1, char 5: unterminated `s' command
sh: .mod.c/: not found
Comments on an earlier patch sought an all-perl implementation.
