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.

defcd5e75e Fix a segfault by only constructing the prompt when we need to. If we don't 
do this we will segfault processing /etc/.profile since cwd isn't yet set.

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.

b2356f6de9 Patch from Matt Kraai to fox sh.c escape problem such that 
running things like 'echo "\n\tHi\n\t\!"' and 'echo -e "\n\tHi\n\t\!"'
behave as under bash.

his patches a bit and all looks good now...

8c725e624a Patch from Larry Doolittle (with minor touchups from me so everything compiles 
and works) to use the applet definitions in applets.h to autogenerate the applet
function and usage prototypes.

46f0beb167 Patch from Gennady Feldman <gfeldman@tradeline.net> to: 
1. Opens redirections w/ the right access.
    2. Doesn't do globbing for every single parameter (so it
	doesn't stat every parameter).

exit rather than segfaulting (what an improvement).

to using getopt and cleaned up the resulting mess.  if-then-else-fi
is now basically working (given a bunch of constraints).

6a99aaf020 More shell features.... if-then-else-fi is now basically usable (disable 
by default pending further debugging).  Added in some basic shell environment
support (i.e. $?, $0-$9, $$, $!, $#).

a1d187a8a8 Backtick support to infinite (memory limited) levels of nesting is 
now implemented...  So now busybox shell can do cool stuff like:

    /home/andersen/CVS/busybox # echo foo `wc README` bar
    foo 71 422 2951 README bar

I love writing cool new features....  Muhahahaha...  (I think this is
leaking a little bit of memory every time it expands a backtick process,
so I still needs to do a bit of cleanup...)
