get_verbatim_kbinput() should use an int*, not a char*, for consistency
with get_kbinput()

Also, with keypad() set to TRUE, xterm generates KEY_BACKSPACE
when the user hits Ctrl-H, which, when cut down to ASCII
range, ends up being Ctrl-G, which can be confusing. (DLR)
+ - For consistency with get_kbinput(), use an int* to store and
+ return the input instead of a char*, and tweak the functions
+ that call it to handle this. (DLR)
get_accepted_kbinput()
- Don't use "kbinput = wgetch(win)" as a switch value. (DLR)
get_escape_seq_kbinput()
- Add support for the escape sequences for F1-F14 whenever
possible (i.e, whenever a conflict doesn't occur), some
additional comments, and a few cosmetic cleanups. (DLR)
+ - Use switch statements instead of strncmp() to read in the long
+ xterm sequences for Ctrl-[arrow key] and Shift-[arrow key].
+ (DLR)
get_escape_seq_abcd()
- A resurrected version of the old abcd() function, readded in
order to simplify get_escape_seq_kbinput(). (DLR)
