CONFIG_ symbol in the kernel, and this clashes with busybox's CONFIG_TR
and CONFIG_WATCHDOG, causing applets.h to barf if they're not switched
on (since the broken headers don't affect kconfig or the makefiles).
Since such broken kernel headers are common enough to crop up every few
months, a simple work around is to move TR and WATCHDOG from CONFIG_
to ENABLE_ early.

Remind me to add a test suite for this thing. I think I've figured out
how to handle root-only testsuites...

exception of whitespace differences on last lines of output with
non-uniform length, which are neither fixed nor worsened by this
change.)

problem was that the buffer used for "." command ("last_modifying_cmd")
wasn't being maintined correctly -- the recording code was walking back
over the front of that buffer when a repeatable insert command
included backspacing (e.g. "i\b\b\bfoo"). the fix is to simply
record the backspaces along with the rest of the command.
also, cleaned up start_new_cmd_q() slightly.
sed.tests file. My brain hurts now. (Lots of boggling at sed minutiae and
corner cases and going "why is gnu giving that output". The behavior of N
and n with regard to EOF are only understandable if you read the Open Group
spec, not if you read the sed info page, by the way...)
Some of the existing sed tests are just nuts. For example, sed-next-line is
testing for our behavior (which is wrong), and would fail if run against gnu
sed (which was getting it right. Again, this was a spec-boggling moment,
with much head scratching. I've got to add a debug mode where the stuff
output by the p command is a different color from the stuff output by normal
end of script printing (when not suppressed by -n).)
As for sed-handles-unsatisifed-backrefs: what is this test trying to _do_? I
ran it against gnu sed and got an error message, and this behavior sounds
perfectly reasonable. (It _is_ an unsatisfied backref.) The fact we
currently ignore this case (and treat \1 as an empty string) isn't really
behavior we should have a test depend on for success.
The remaining one is sed-aic-commands, which is long and complicated. I'm
trying to figure out if I should chop this into a number of smaller tests, or
if having one big "does-many-things" test is a good idea.
In any case, the _next_ step is to go through the Open Group standard and
make tests for every case not yet covered. (And there are plenty. There
are few comments in the file already.) Plus I have notes about corner
cases from development that I need to collate and put into here. This file
is maybe the first 1/3 of a truly comprehensive sed test.

So we can compare against non-busybox versions, and possibly our testsuite
will be useful to somebody like the Linux Test Project someday.
Redid testing.sh to add new command, "optional", to skip tests that require
certain features. (use: `optional FEATURE_SORT_BIG`, or `optional ""` to
stop skipping.) Note that optional is a NOP if the environment variable
"OPTIONFLAGS" is blank, so although we're marking up the tests with busybox
specific knowledge, it doesn't interfere with running the tests without
busybox.
Moved setting the "OPTIONFLAGS" environment variable to runtest. Philosophy:
busybox-specific stuff belongs in runtest; both testing.sh and the tests
themselves should be as busybox-agnostic as possible.
Moved detecting that a command isn't in busybox at all (hence skipping the
entire command.tests file) to runtests. Rationale: optional can't currently
test for more than one feature at a time, so if we clear anything with
optional "" we might perform tests we don't want to.
Marked up busybox.tests to know which tests need CAT enabled. Fixed up other
tests to be happy with new notation.
I suspect egrep should be appended to grep. It's a sub-feature, really...
chunk of data when they get it and not block until they've buffered 4k.
The use case was cat /proc/psaux, but you can also reproduce this by
running non-busybox cat by itself and typing things at the command line.
Then run busybox cat. Notice how cat is _supposed_ to echo each line back
to us as we hit enter?
