/*
 *	captoinfo.c --- conversion between termcap and terminfo formats
 *
 *	The captoinfo() code was swiped from Ross Ridge's mytinfo package,
 *	adapted to fit ncurses by Eric S. Raymond <esr@snark.thyrsus.com>.
 *
 *	There is just one entry point:
 *
 *	char *_nc_captoinfo(n, s, parameterized)
 *
 *	Convert value s for termcap string capability named n into terminfo
 *	format.
 *
 *	This code recognizes all the standard 4.4BSD %-escapes:
 *
 *	%%       output `%'
 *	%d       output value as in printf %d
 *	%2       output value as in printf %2d
 *	%3       output value as in printf %3d
 *	%.       output value as in printf %c
 *	%+x      add x to value, then do %.
 *	%>xy     if value > x then add y, no output
 *	%r       reverse order of two parameters, no output
 *	%i       increment by one, no output
 *	%n       exclusive-or all parameters with 0140 (Datamedia 2500)
 *	%B       BCD (16*(value/10)) + (value%10), no output
 *	%D       Reverse coding (value - 2*(value%16)), no output (Delta Data).
 *
 *	Also, %02 and %03 are accepted as synonyms for %2 and %3.
 *
 *	Besides all the standard termcap escapes, this translator understands
 *	the following extended escapes:
 *
 *	used by GNU Emacs termcap libraries
 *		%a[+*-/=][cp]x	GNU arithmetic.
 *		%m		xor the first two parameters by 0177
 *		%b		backup to previous parameter
 *		%f		skip this parameter
 *
 *	used by the University of Waterloo (MFCF) termcap libraries
 *		%-x	 subtract parameter FROM char x and output it as a char
 *		%ax	 add the character x to parameter
 *
 *	If #define WATERLOO is on, also enable these translations:
 *
 *		%sx	 subtract parameter FROM the character x
 *
 *	By default, this Waterloo translations are not compiled in, because
 *	the Waterloo %s conflicts with the way terminfo uses %s in strings for
 *	function programming.
 *
 *	Note the two definitions of %a: the GNU definition is translated if the
 *	characters after the 'a' are valid for it, otherwise the UW definition
 *	is translated.
