Summary: obtuse shell scripting in profiling docs

Initial Comment:
Hi!  I'm looking at this page:

http://haskell.org/ghc/docs/latest/html/users_guide/hp2ps.html

I see a shell command like this:

head -`fgrep -n END_SAMPLE FOO.hp | tail -1 | cut -d :
-f 1` FOO.hp     | hp2ps > FOO.ps


It looks like a complex way of saying:

grep END_SAMPLE FOO.hp | hp2ps > FOO.ps


The mantra is repeated a few times in that section, and
(assuming I'm not missing something) should be
simplified in each place.

Regards,

Tim Smith <tim@xxxxxxxxxx>
