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.

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).
