Create TERMCAP entries limited to 1023 bytes by default.

​

TERMCAP_BUF defaults to 1023 to create TERMCAP entries that work on

most systems.  To save space, TERMCAP is unwrapped, and vt220 extra

keys are skipped (unless TERMCAP_BUF > 1023); navigation keys are

still included.  Entries larger than TERMCAP_BUF are now truncated,

and no longer Panic screen.

​

Termcap entries are still wrapped when saved to a file.

​
