4987bbf979 A fix from Larry Doolittle for some nasty segfaults when sh.c tried to free a 
corrupted cmd pointer, and where it would truncate a command line at the first
double space.

1365bb7861 When using wordexp, only try to use the expand command 
when something actually got expanded.  Skip it otherwise.

74e056bfc8 Fixed a couple more cases. $FOO/bar ${FOO} and such now work 
without wordexp.  Of course for stuff like ${1:-foo} you still
need wordexp for them to work.

195743f195 Ok, sh.c should be working now. Many thanks to Larry Doolittle 
for his timely help -- nearly all of the work in this patch is
his.

single argument commands.  It should now work as expected...

32f8c170b0 Remember to delete un-expandable variables, and do a better job of expanding 
shell-specific things in case the wordexp implementation is broken (ie. the
stubbed out wordexp in uClibc).

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
be ever so standards compliant.   This change needs testing by everyone, but
appears to be solid enough to let us close bug #1090.

It works for me; however, please test this change!

54851d3c65 Fixed a memory leak in lash. It seems that close_all was calling close() 
directly instead of calling mark_closed(), which allowed the memory allocated
by mark_open() to never be freed.

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.

67991cf824 This patch, put together by Manuel Novoa III, is a merge of work 
done by Evin Robertson (bug#1105) and work from Manuel to make
usage messages occupy less space and simplify how usage messages
are displayed.

af4ac77d9d Apply a patch from Larry Doolittle to add "-all" and "-none" switches 
to multibuild.pl.  I did a little formatting adjustments to make it
_very_ obvious when things stop working.  I also removed the USE_PROCFS
config option -- just do the right thing when USE_DEVPS_PATCH is enabled.

b0970d4fed Patch from Larry Doolittle to set values to static variables that live in the 
bss at runtime, since sh.c can call sh.c, which causes these variables to not
be set to their defaults as god intended.

e9f07fb6e8 Another sh.c patch from Larry Doolittle. This makes redirects work properly 
with non-forking shell builtins.  Especially helpful for "read".  This patch
also beautifies builtin_fg_bg, clarifies the problems with
run_command_predicate, makes if/then/else support the default, and corrects the
sense of the BB_FEATURE_SH_ENVIRONMENT comment.

70da6a66d2 Fix a warning in sh.c. Remove use of getline() in md5sum since 
nobody else uses it and it is a GNU extension anyways...

86349776d0 Ok, this is a pretty major update to sh.c. I renamed all the variables and 
function names to conform with the style guide.  I also did a lot of work on
the if-then-alse-fi logic and added prototype (i.e. it segfaults when enabled)
line continuation support.

Furthermore, this patch includes Larry Doolittle's work on restructuring some
of the data structures that represent the job and child_program, allowing
several simplifications and fixing several bugs.
