* FUNCTION

* AUTHOR
*
* POV-Ray Team
*
* DESCRIPTION
*
* Parses a traditional POV-Ray command-line switch that starts
* with + or -. Whenever it seemed feasible, calls process_variable
* to perform the function rather than doing so itself. Although this
* requires another pass through a switch{case, case...}, it insures
* that command-line switches and variable=value options get treated
* identically.
*
* CHANGES
*
* -
*
* Sep 1994 : Added options for union splitting, vista/light buffer. [DB]
* Jan 1995 : Added options for histogram grid. [CJC]
* Feb 1995 : Added options for console/file redirection and .INI writing [SCD]

* Given a string containing a line of text, split it into individual
* switches or options and then pass them off to be parsed by parse_switch
* or process_variable. This routine is called by parse_ini_file,
* by the main with argv[] and by READ_ENV_VAR_????

* CHANGES
*
* Mar 1996 : Allow ';' in an option, if it is escaped [AED]
