tweaks to perl helpers

`perlfind -f` really should be printing one result per line, so now it is
`perl-privatize -d` was way too stupid in its attempt to find the "real" copy to diff against
-	this way should be much smarter
-	although probably still not 100% perfect
added a `perl-privatize -t` to do the equivalent of this:
-	`perl-privatize Some::Module ; pfind -e Some::Module ; perl-privatize -r Some::Module`
-	much neater now, and much more efficient than the above
finally getting rid of duplicate copy of perlfind
fix some clgrep display issues

don't restore quoted strings/comments if they're _before_ the keyword we're searching for
-	(eliminates long leading comments before the target line)
chop some extranneous dirs off the front of the file path to make it not use up so much screen real estate
don't expand tab until _after_ restoring quoted strings/comments
the fortunes file was rife with extranneous spaces!
added some Erma Bombeck quotes
