4896bdf6de Revert "Make grep more memory-efficient"
This reverts commit d9a098ae6bc07188cbaefcd188e5911dec41815d.

Conflicts:
	grep.c

Hiltjo Posthuma <hiltjo@codemadness.org> said:

(Re)compiling the regex for each line doesn't make sense (imho) and
slows it down a lot.

A simple test:

time seq 1 100000000 | grep 'a'

sbase grep (before patch):
    0m22.21s real     0m0.00s user     0m0.00s system

sbase grep (after patch):
    2m16.28s real     0m0.00s user     0m0.00s system

coreutils grep:
    0m1.15s real     0m0.00s user     0m0.00s system

So the patch should be reverted I think.

e6238dda31 grep: Remove trailing newline before trying to match RE
This unbreaks the "$" operator
and some uses of grep with other REs
(e.g. 'grep . TODO' to remove empty lines).
