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.

typos in #ifdef DEBUG

Hi tech@

While building a kernel with option DEBUG to try to hunt down my issue 
with the Libretto 70CT (PR 6052) I came across the following typos which 
prevented the build:


sys/arch/i386/i386/trap.c
