Back out do_prev_word and SMALL changes, as the prev function is obviously not stable enough

   cut_marked_segment()
 	- Fix off-by one in mem allocation.
 - nano.c:
-	- Backported do_prev_word() from 1.1.  Allows alt-space to 
-	  move to the previous word in the file.
-	- Added #ifdef NANO_SMALL around do_next_space and do_prev_space
-	  codes, as nano-tiny doesn't particularly need those features.
