lpr suite uses getcap(3) so this is never used!

- * printcap - routines for dealing with the printer capability data base

- * BUG:		Should use a "last" pointer in tbuf, so that searching
- *		for capabilities alphabetically would not be a n**2/2
- *		process when large numbers of capabilities are given.
- * Note:	If we add a last pointer now we will screw up the
- *		tc capability. We really should compile printcap.
- *
- * Essentially all the work here is scanning and decoding escapes
- * in string capabilities.  We don't use stdio because the editor
- * doesn't, and because living w/o it is not hard.
