Hi Mike, Hi to all,
This patch contains just some trivial changes to reduce the size of tune2fs.
The changed code is left commented out so that it is easier to inspect it.
This is not intensively tested :)
Size reduction is:
   text    data     bss     dec      hex    filename
   6931      20     144    7095    1bb7 tune2fs.o.orig
   6737      20     144    6901    1af5  tune2fs.o

Ciao,
Tito
