acd647c877 Joe.C writes: 
This bug is in busybox 1.0.0-rc2. When using lash exec
builtin with redirection, the opened file fd keep increasing.
For example, please try the following command with lash.


ls -al /proc/<lash pid>/fd
exec /bin/sh 2>/dev/null
ls -al /proc/<lash pid>/fd

  The last 'ls' command output will look like this. The fd
number 4 shouldn't exist.

lrwx------    1 501      100         64 Aug 13 13:56 4 -> /dev/pts/5
l-wx------    1 501      100         64 Aug 13 13:56 2 -> /dev/null
lrwx------    1 501      100         64 Aug 13 13:56 1 -> /dev/pts/5
lrwx------    1 501      100         64 Aug 13 13:56 0 -> /dev/pts/5
dr-xr-xr-x    3 501      100          0 Aug 13 13:56 ..
dr-x------    2 501      100          0 Aug 13 13:56 .

  This one-line patch fix this problem by setting CLOEXEC flag for
squirrel fd. Please apply.

It looks like latest uClibc defines ARCH_HAS_MMU, but a few busybox files
test UCLIBC_HAS_MMU, resulting in vfork() getting called instead of
fork(), etc.

Patch below.   Only tested for lash.

f594986b37 - Changed name of BB_FEATURE_SIMPLE_PROMPT to BB_FEATURE_SH_SIMPLE_PROMPT 
- Set BB_FEATURE_SH_STANDALONE_SHELL and BB_FEATURE_SH_APPLETS_ALWAYS_WIN to
   be off by default
 - Set BB_FEATURE_SH_SIMPLE_PROMPT to be on by default
 - Added some more magic to the Olympus section to make all the dependencies
   on the shell, cmdline editing, tab completion and friend work properly.
 - Tidied up the Olympus section with some whitespace. Checked the various
   scrips that parse through there and the extra whitespace shouldn't break
   anything.

ca6045955d Rework environment variable handling to use wordexp, per a suggestion from 
Larry Doolittle a couple of months ago.  This makes the stuff-expansion in lash

appears to be solid enough to let us close bug #1090.

caeeb36784 This fixes lash so it handles environment variable expansion, regardless 
of where the environment variables are located in an argument.  This allows
things like 'echo foo$1$SHELL' to expand the same way bash would expand it.
Of course, to make this work I introduced a memory leak, and I am too tired
to find a way to fix it.

6faae7deb4 Commit Vladimir's latest cmdedit. I modified it slightly to ensure 
parse_prompt() would be called before cmdedit_init(), since cmdedit_init()
calls cmdedit_setwidth() which uses cmdedit_prmt_len, which is set by
parse_prompt().  Also, added a mod, so very narrow terminals should now wrap
properly...  This is working very nicely for me -- Vladimir has done some
very good work.
