udhcpc: don't exit after backgrounding on -n -b
Currently, running "udhcpc -n -b" causes udhcpc to go to background and
then exit after some time unless a lease is obtained.
It's not very useful to do so
as the calling process doesn't know
if the lease was obtained or not anyway.
The code actually tries to favor "-b" over "-n",
but doesn't clear "-n" flag while clearing "-b" after backgrounding.
So, clear "-n" flag after going into background.
This effectively makes "-b" override "-n" completely
and "-n -b" behave the same as "-b".
This allows to override default "-n" option, passed to udhcpc by ifupdown,
without recompiling busybox.

Commit
bb983f30e (vi: fix faulty undo after autoinsert) has a
number of problems:
- The commit message refers to 'autoinsert' when it really means
'autoindent'.
- The indentation of undo_push_insert() was incorrect.
- Most seriously the commit only fixed the problem for cases where
the indentation was exactly one character. This is because undo_push()
only allows single characters to be queued for UNDO_INS_QUEUED.
Lifting this restriction allows the example given in the previous
commit message (with a three character indent) to work.

grep: fix -x -v with certain pattern orders
We found out that busybox -x -v is a bit broken:
ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -e 'aa.*' -e '.*bb.*'
aa bb cc
ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -v -e 'aa.*' -e '.*bb.*'
ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -e '.*aa.*' -e 'bb.*'
aa bb cc
ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -v -e '.*aa.*' -e 'bb.*'
aa bb cc
Last one is wrong.
This patch fixes the issue by making sure that the variable 'found'
never makes a transition from 1 to 0, as this would mean that
grep previously found a match on this input line.
