trylink: explain how to modify link and drastically decrease amount
of padding (unfortunately, needs hand editing ATM).
*: add ALIGN1 / ALIGN2 to global strings and arrays of bytes and shorts
size saving: 0.5k

*: s/include "busybox.h"/include "libbb.h"

Seen in the testsuite for du -l .../testsuite on exit with CLEAN_UP enabled.

Found bad typo in largefile support :)

It is impossible to formulate sane ABI based on
size of ulong because it can be 32-bit or 64-bit.
Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
Make it explicit.

2) better support long options
3) new flag '!' for bb_opt_complementally: produce bb_show_usage() if BB_GETOPT_ERROR internally

Manuel,
I rewrite bb_getopt_ulflags() function for more universal usage.
My version support now:
- options with arguments (optional arg as GNU extension also)
- complementaly and/or incomplementaly and/or incongruously and/or list
options
- long_opt (all applets may have long option, add supporting is trivial)
This realisation full compatibile from your version.
Code size grow 480 bytes, but only coreutils/* over compensate this size
after using new function. Last patch reduced over 800 bytes and not full
applied to all. "mkdir" and "mv" applets have long_opt now for demonstrate
trivial addition support long_opt with usage new bb_getopt_ulflags().
Complementaly and/or incomplementaly and/or incongruously and/or list options
logic is not trivial, but new "cut" and "grep" applets using this logic
for examples with full demostrating. New "grep" applet reduced over 300
bytes.
Mark,
Also. I removed bug from "grep" applet.

and then fixed up df, du, and ls to use the new interface. I also
fixed up some formatting issues in ls while I was in there.

This way, we can new get rid of all that tedious #define rubbish we used to
need to enable specific messages. This way is enormously simpler, and as a
bonus also ends up saving us 96 bytes.

'format' function to 'make_human_readable_str'.

since my last pass only fixed 'du -h' but left the others broken.

header file usage before the 0.49 release. To fix it, I had to move
the '#include "busybox.h"' to the end of the list of #include files.

done by Evin Robertson (bug#1105) and work from Manuel to make
usage messages occupy less space and simplify how usage messages
are displayed.

busybox.h which slowed compiles. I left only what was needed and then fixed up
all the apps to include their own header files. I also fixed naming for pwd.h
and grp.h functions. Tested to compile and run with libc5, glibc, and uClibc.

Add support for -k in du, df, and ls(no define, it's for compatibliity with the GNU utils as bb does -k by default)
Fix bug #1084
