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.

vi: further fixes to undo after autoindent

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.

passwd: initialize pointers correctly

Fix regression from commit 17058a06c4333fc0c492c168c8a971ebd0fd5a5a
Root user never changes the orig pointer, so when cleaning up, passwd tried to
free orig=(char*)""
Example: sudo passwd $USER
Changing password for xxx
New password:
Bad password: too short
Retype password:
Passwords don't match
free(): invalid pointer
