The F13-F24 support can be considered a completely separate issue to the colour 
and attribute support.

OpenBSD doesn't assign funcions to F13-F24 by default, but the scancodes 
generated by a standard PC-122 terminal keyboard, (such as the ones from 
Unicomp), as recognised as F13-F24 since a few releases back.  Any use of 
F13-F24 would presumably be defined locally, so the fact that they are not 
available on all keyboards shouldn't be an issue.

However, until now the escape codes generated for F13-F24 were not listed in 
any of the three terminfo entries that are generally used, vt220, pcterm or 
xterm.  I created a custom terminfo entry to fix this for local use here, and 
then went on to address the issue of colour on the console whilst I was looking 
at it.

I'll wait for input from Nicholas and Alexei before doing any more to this 
patch :-).
