/*
* Capabilities from termcap
*
* The description of terminals is a difficult business, and we only
* attempt to summarize the capabilities here; for a full description
* see the paper describing termcap.
*
* Capabilities from termcap are of three kinds - string valued options,
* numeric valued options, and boolean options. The string valued options
* are the most complicated, since they may include padding information,
* which we describe now.
*
* Intelligent terminals often require padding on intelligent operations
* at high (and sometimes even low) speed. This is specified by
* a number before the string in the capability, and has meaning for the
* capabilities which have a P at the front of their comment.
* This normally is a number of milliseconds to pad the operation.
* In the current system which has no true programmible delays, we
* do this by sending a sequence of pad characters (normally nulls, but
* specifiable as "pc"). In some cases, the pad is better computed
* as some number of milliseconds times the number of affected lines
* (to bottom of screen usually, except when terminals have insert modes
* which will shift several lines.) This is specified as '12*' e.g.
* before the capability to say 12 milliseconds per affected whatever
* (currently always line). Capabilities where this makes sense say P*.
