There is as always a different, and i think simpler, way to get a count
of how many files match the pattern.

grep -rl searchstring . --include \*.html | wc -l

the options to grep say to recurse, only print the filename once for
each match, and only check .html files (note the \ to stop the shell
expanding the *).  which gives you a list of filenames one per line, so
we simply ask wc to count the lines for us.
