Implement a -H flag for grep, useful for combining e.g. find and grep.
-o used to do this but has been removed. (See the commit logs for the reason, i
forgot it)
grep(1) only prints the filename when it receives more then 1 filename as
arguments. Thus, when you do this:
$ find . -name '*.c' -exec grep bla {} \;
It doesn't print the filename.
But when you use xargs(1), like Bret suggests it does.
$ find . -name "*.php" -exec grep blah {} \; -print
Will print the file name after the line that grep matches.
