interix termcap and terminfo
Dear Martin Köppe,
Thomas E. Dickey sent me the following when I asked if he might explain the details of what the /usr/share/termcap and /usr/share/terminfo.src patches fix; maybe you also have some input as you might be more familiar with SFU/SUA Interix.
Sincerely,
Eric Lindblad

The termcap patch is changing the delete-character key, apparently
someone confusing it with the backspace key:
key_dc kdch1 kD delete-character key
key_backspace kbs kb backspace key
That's not the way it's conventionally assigned. Whether backspace is \177
or ^H depends mostly on whether the developer prefers Linux to other platforms.
The changes to RI and SF are okay (the "%d" is the parameter):
parm_index indn SF scroll forward #1
lines (P)
parm_right_cursor cuf RI move #1 characters
to the right (P*)
It misses a similar change for SR (there should be a '[' after each occurence
of \E in the control sequences - not the function keys beginning with 'k').
The terminfo changes make the same modification of the delete-character
key, as well as adding definitions for the home and insert keys. In
the latter I have the insert-key in ncurses, but no definition for a home
key. It might be correct - might not (might be cut/paste). On most
PC-keyboards, home/end are on the editing keypad and often are \E[H (or
\EOH) and \E[F (or \EOF). It won't do any harm to keep that bit.
The terminfo's strings for indn and cuf look okay. In ncurses I have
