This patch reduces code size by 224 bytes on my Core 2 with gcc 4.4.1:

text data bss dec hex filename
15767 0 8 15775 3d9f lib/vsprintf.o-before
15543 0 8 15551 3cbf lib/vsprintf.o-after

and implements some cleanups.

v3: improved comments on patch 5/7 and factorize a switch statement on 6/7
as per suggestions from Ingo and Frederic (thanks!)
v2: addressed feedback from Frederic Weisbecker review (thanks!!)
and split into separate patches
v1: original submission

André Goddard Rosa (7):
vsprintf: factorize "(null)" string
vsprintf: pre-calculate final string length for later use
vsprintf: give it some care to please checkpatch.pl
vsprintf: use TOLOWER whenever possible
vsprintf: reduce code size by avoiding extra check
vsprintf: move local vars to block local vars and remove unneeded ones
vsprintf: factor out skip_space code in a separate function
