We should be POSIX compliant now.

afa2e6ec54 Use SLIST_* instead of TAILQ_* in grep(1)
The order of evaluation is unspecified by POSIX so we do not need
to process the patterns in-order.

e17b9cdd0a Convert codebase to use emalloc.c utility-functions
This also definitely increases readability and makes OOM-conditions
more consistent.

ec8246bbc6 Un-boolify sbase
It actually makes the binaries smaller, the code easier to read
(gems like "val == true", "val == false" are gone) and actually
predictable in the sense of that we actually know what we're
working with (one bitwise operator was quite adventurous and
should now be fixed).

This is also more consistent with the other suckless projects
around which don't use boolean types.

It was about damn time. Consistency is very important in such a
big codebase.

1ca8a314f8 grep: Remove newlines before matching a line
Otherwise, a pattern with a '$' anchor will never match and POSIX says that

  "By default, an input line shall be selected if any pattern ... matches any
   part of the line excluding the terminating <newline>"

97fb4a1f9c grep: improvements
improvements:
- improve statuscode behaviour
  - don't exit if a file in a series fails. exit 2 if an error occured
    in a file series. don't exit if there is a read error (like: grep
     input file is a directory).
- use agetline instead of agets().

with the simple test: time seq 1 100000000 | grep 'a'
its 12 seconds (from 24 seconds) on my machine.

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).
