...which is why I renamed it "bgrep" here.

Incidentally, two comments about bm. One is that the
manual alleges you can search for multiple patterns, but I can't
seem to get it to work. (The manual talks about newline-separated
patterns, but
$ bgrep 'pat1
> pat2' *.c
seems to find only pat2.

The other is,I wonder whether ^ and $ could be implemented quite
easily within bm, essentially by mapping them into \n. That would
let bgrep "^name" /etc/passwd, for example, work fast (we have
2,000 entries in our /etc/passwd).
