* char *
* tparm(string, ...)
*
* Substitute the given parameters into the given string by the following
* rules (taken from terminfo(5)):
*
* Cursor addressing and other strings requiring parame-
* ters in the terminal are described by a parameterized string
* capability, with like escapes %x in it. For example, to
* address the cursor, the cup capability is given, using two
* parameters: the row and column to address to. (Rows and
* columns are numbered from zero and refer to the physical
* screen visible to the user, not to any unseen memory.) If
* the terminal has memory relative cursor addressing, that can
* be indicated by
*
* The parameter mechanism uses a stack and special %
* codes to manipulate it. Typically a sequence will push one
* of the parameters onto the stack and then print it in some
* format. Often more complex operations are necessary.
*
* The % encodings have the following meanings:
*
* %% outputs `%'
* %c print pop() like %c in printf()
* %s print pop() like %s in printf()
* %[[:]flags][width[.precision]][doxXs]
* as in printf, flags are [-+#] and space
* The ':' is used to avoid making %+ or %-
* patterns (see below).
*
* %p[1-9] push ith parm
* %P[a-z] set dynamic variable [a-z] to pop()
* %g[a-z] get dynamic variable [a-z] and push it
* %P[A-Z] set static variable [A-Z] to pop()
* %g[A-Z] get static variable [A-Z] and push it
* %l push strlen(pop)
* %'c' push char constant c
* %{nn} push integer constant nn
*
* %+ %- %* %/ %m
* arithmetic (%m is mod): push(pop() op pop())
* %& %| %^ bit operations: push(pop() op pop())
* %= %> %< logical operations: push(pop() op pop())
* %A %O logical and & or operations for conditionals
* %! %~ unary operations push(op pop())
* %i add 1 to first two parms (for ANSI terminals)
*
* %? expr %t thenpart %e elsepart %;
* if-then-else, %e elsepart is optional.
* else-if's are possible ala Algol 68:
* %? c1 %t b1 %e c2 %t b2 %e c3 %t b3 %e c4 %t b4 %e b5 %;
*
* For those of the above operators which are binary and not commutative,
* the stack works in the usual way, with
* %gx %gy %m
* resulting in x mod y, not the reverse.
