Single capability strings in some termcap databases are bigger
than 1K.  I really saw a coredump in a previous version of zsh.
The fix for that version was:

	--- ./src/zsh.h 1995/12/07 21:40:24     1.1
	+++ ./src/zsh.h 1996/10/23 16:18:58
	@@ -1855,7 +1855,7 @@
 
	 /* the termcap buffer */
 
	-EXTERN char termbuf[1024];
	+EXTERN char termbuf[4096];
 
	 /* $TERM */
