backstroke should delete entire entry, not just one letter at a time

[will]

this is useful because its faster to do one backstroke and re-type the word than doing numerous backstrokes for each letter.

• note

when there is no word being typed (when the work bar is empty), backstroke should remain as deleting one letter at a time.

see the qtopia keyboard for more details.

This is not actually possible given standard keyboard input. as best i know even xinput and complex input systems can't do this, so i have to mark this as "wontfix". the ONLY way todo this is to go to every toolkit and extend it with a "delete previous word" command that is reliably accessible for an input system (qt, gtk, efl etc.) and that's not going to be a happening thing any time in the near future (as i either need to ASSUME some ctonrol-key sequence like ctl+shift+w or something, or a special keycode mapped to a special keysym or need to look at a full input method handler like scim/uim etc.). :(
