Should be a big win for libbusybox. busybox wins too:
text data bss dec hex filename
776524 929 9100 786553 c0079 busybox_old
775903 929 9100 785932 bfe0c busybox_unstripped
(one which strips trailing slash and one which does not)
wget: straighten out as a result of above change
text data bss dec hex filename
5056 1 0 5057 13c1 busybox.t4/networking/wget.o
5022 0 0 5022 139e busybox.t5/networking/wget.o
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
correct_password: explain in detail why it is ok to use bb_banner
fsck_minix: make it print bb version, not it's own (outdated/irrelevant) one
Marginal size difference:
text data bss dec hex filename
679119 2700 15632 697451 aa46b busybox_old
679091 2700 15632 697423 aa44f busybox_unstripped
applets: do not even try to read config if run by real root
msh: use named constants (O_RDONLY etc) in open() instead of magic numbers,
other minor code size reduction.
and now this fact is recorded in applets.h, not ash.c.
Several fixes to "--help + STANDALONE_SHELL" scenarios.

./busybox ash -c 'i=20000; while test $i != 0; do touch z; i=$((i-1)); done'
runs more than twice as fast with STANDALONE_SHELL versus without.
