examples/udhcp/simple.script: fix resolv.conf update if it is a dangling symlink

already exist, "readlink -f" will not detect it as symlink. Explicitely check
for that condition before and touch the file, making the other code work as
intended.

If a configuration file lists the default path first:
MANPATH /usr/man:/usr/share/man

it. As a result man_path_list only contains the second and subsequent

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.

ash: eval: avoid leaking memory associated with redirections. Closes 7748
The following constructs result in ever-increasing memory usage:

For comparison, bash displays static memory usage in both cases.
This has been fixed in dash by commit

I have simplified evaltree so that it simply sets the stack mark

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.
