[PATCH][RFC] forward/backward a word facility

[Daniele Bellucci]

Hi All,

this is a little patch for grub-0.93 to add te following
cmdline features:
- C-g: move backward a word 
- C-l: move forward  a word

patch looks good to me and works fine too ... but i'm not sure
if these features are really needed.
I need them with long linux kernel boot parameters (for example:
the recent kgdb-overethernet require at least 5 boot parameters)

BTW feedbacks are much appreciated, and if the mantainer would 
like to apply this patch i'll be very glad to patch "grub info " too.

so, comon: give me some feedbacks 8))
