044228d5ec This is vodz' latest patch. Sorry it took so long... 
1) ping cleanup (compile fix from this patch already applied).
    2) traceroute call not spare ntohl() now (and reduce size);
    3) Fix for functions not declared static in insmod, ash, vi and mount.
    4) a more simple API cmdedit :))
    5) adds "stopped jobs" warning to ash on Ctrl-D and fixes "ignoreeof" option
    6) reduce exporting library function index->strchr (traceroute), bzero->memset (syslogd)

1c03923b0b Add in a shell tagline (per lash/hush behavior) to make it easier 
to know which shell is in use.  Add in 'help' to list available
builtins, and fixup msh so it can do STANDALONE_SHELL.

8df319b213 A bit of testing today showed that ASH_BBAPPS_AS_BUILTINS was 
totally breaking the shell.  Simple thinge like 'FOO=100' caused
it to segfault.  It turns out that disabling "bltincmd" is a very
bad idea.

2870d964f8 Some updates to ash from vodz. Makes ash smaller. I made a few 
changes, esp describing all the current ash configuration options.
Now ash adds 66k in the default configuration.

ff9eee475f This is a busybox port of the Minix shell. It is reasonably capable, 
handles all the basic stuff (for, case/esac, while, if/then/else), and
is very small (adds just 38k on x86).  It is not as rigorously correct
about Bourne semantics as bash, but for most things it is quite
workable.  There is still some work to be done to further shrink it (it
has its own globbing functions instead of using the libc ones, for
example), but it is quite usable as is.

cb57d551a2 This a an ash applet I put together. It is similar to the one put 
together by vodz, but uses newer sources, has the removed features
commented out instead of simply deleted (so they could be re-enabled)
and the builtins all work.  This adds 72k.

just be a simple command line interpreter with basic pipe, redirect, and job
control.  For all the more fancy things, people should use hush or ash.

04407e522b Another hush update from Larry: 
Fixes the interaction between if/then/else/fi syntax and variables.
    I planned to do it right from the beginning, but my implementation
    was buggy.  Also adds the relevant test cases.  Also adds some old
    Matt Kraai variable test cases that got left out somehow.

Valdimir's patch missed two cases of local variable handling
    FOO=bar
    export FOO=baz
    unset FOO
and
    export FOO=bar
    FOO=baz
which were working before, so I fixed those two cases.

bfae2529b8 It turns out job control in both hush and lash was broken by the 
signal handling in cmdedit.c.  Disabling it makes the shells behave
themselves again.  hush isn't quite there, but is getting close...
