***************************************************************************
*
* Mnemonic: FMcmd
* Abstract: This routine is responsible for dispatching the proper
* routine to handle the command that was input by the user.
* Commands are those tokins that begin with a period and are 2
* characters long.
* Parms: buf - Pointer to the command. (.aa)
* Returns: Nothing.
* Date: 17 November 1988
* Author: E. Scott Daniels
*
* Modified: 1-1-89 - To support normal and definition lists
* 4-30-98- To support user defined list item characters
* 5-05-89- To support boxes
* 6-10-89- To add .** as a comment line in the input file
* 3 May 1991 - To support .ts (two sided) command
* 4 May 1991 - To support page shifting
* 5 May 1992 - To support postscript
* 1 Oct 1992 - To support punctuation space command
* 2 Nov 1992 - To add center command
* 13 Nov 1992 - To free/malloc current font buffer
* 3 Dec 1992 - To flush before setting font size or font
* 6 Jun 1993 - To set y position for list item bullets higher
* 21 Feb 1994 - To handle shift value in dlstack rather than old
* left margin; correct multi column problem
* and to call setstr for running strings
* 21 Oct 2007 - Added index interface
* 26 Jun 2013 - Prevents 0 text size from being set on .st command (happening
* when .st &var and var not defined.
* 03 Jan 2016 - Removed errant flush before FMll() and indent
* calls.

Mnemonic: fmtr
Abstract: start a new row in the current table
Date: 26 Oct 2001 - converted from hfml stuff
syntax: .tr [n] [c=bgcolour] [a=alignval] [r=reserve] [v=valignvalue] [w=weight] [l=linecount]
w= allows the line weight (drawn between the current row and the
new) to be differnt than the default.
m= allows multiple lines to separate the row being terminated from
the next. Lines are spaced fairly close together.
The n option prevents table cell from being called automatically
(user needs to supply a first .cl command).
r= (reserve) will force a column break if the desired amount of
space isn't remaining.
Mods: 10 Apr 2007 -- fixed write of border to be in conditional.
