+/* sigh... this has got to be the ugliest code I've ever written.
+ Trying to handle everything has its cost, I guess.
+
+ It actually isn't to hard to figure out if a given % code is supposed
+ to be interpeted with its termcap or terminfo meaning since almost
+ all terminfo codes are invalid unless something has been pushed on
+ the stack and termcap strings will never push things on the stack
+ (%p isn't used by termcap). So where we have a choice we make the
+ decision by wether or not somthing has been pushed on the stack.
+ The static variable termcap keeps track of this; it starts out set
+ to 1 and is incremented as each argument processed by a termcap % code,
+ however if something is pushed on the stack it's set to 0 and the
+ rest of the % codes are interpeted as terminfo % codes. Another way
+ of putting it is that if termcap equals one we haven't decided either
+ way yet, if it equals zero we're looking for terminfo codes, and if
+ its greater than 1 we're looking for termcap codes.
+
+ Terminfo % codes:
+
+ %% output a '%'
+ %[[:][-+# ][width][.precision]][doxXs]
+ output pop according to the printf format
+ %c output pop as a char
+ %'c' push character constant c.
+ %{n} push decimal constant n.
+ %p[1-9] push paramter [1-9]
+ %g[a-z] push variable [a-z]
+ %P[a-z] put pop in variable [a-z]
+ %l push the length of pop (a string)
+ %+ add pop to pop and push the result
+ %- subtract pop from pop and push the result
+ %* multiply pop and pop and push the result
+ %& bitwise and pop and pop and push the result
+ %| bitwise or pop and pop and push the result
+ %^ bitwise xor pop and pop and push the result
+ %~ push the bitwise not of pop
+ %= compare if pop and pop are equal and push the result
+ %> compare if pop is less than pop and push the result
+ %< compare if pop is greater than pop and push the result
+ %A logical and pop and pop and push the result
+ %O logical or pop and pop and push the result
+ %! push the logical not of pop
+ %? condition %t if_true [%e if_false] %;
+ if condtion evaulates as true then evaluate if_true,
+ else evaluate if_false. elseif's can be done:
+%? cond %t true [%e cond2 %t true2] ... [%e condN %t trueN] [%e false] %;
+ %i add one to parameters 1 and 2. (ANSI)
+
+ Termcap Codes:
+
+ %% output a %
+ %. output parameter as a character
+ %d output parameter as a decimal number
+ %2 output parameter in printf format %02d
+ %3 output parameter in printf format %03d
+ %+x add the character x to parameter and output it as a character
+(UW) %-x subtract parameter FROM the character x and output it as a char
+(UW) %ax add the character x to parameter
+(GNU) %a[+*-/=][cp]x
+ GNU arithmetic.
+(UW) %sx subtract parameter FROM the character x
+ %>xy if parameter > character x then add character y to parameter
+ %B convert to BCD (parameter = (parameter/10)*16 + parameter%16)
+ %D Delta Data encode (parameter = parameter - 2*(paramter%16))
+ %i increment the first two parameters by one
+ %n xor the first two parameters by 0140
+(GNU) %m xor the first two parameters by 0177
+ %r swap the first two parameters
+(GNU) %b backup to previous parameter
+(GNU) %f skip this parameter
+
+ Note the two definitions of %a, the GNU defintion is used if the characters
+ after the 'a' are valid, otherwise the UW definition is used.
