/*
* define the shell's settable options
*
* new options can be defined by adding them here,
* but they do nothing until code to implement them
* is added (using the "var name" field)
*/
/*
* format is up to 5 columns... (followed by anything)
* end of line comments can be introduced by ' #' (space/tab hash) to eol.
*
* The columns are:
* 1. internal shell "var name" (required)
* 2. option long name
* if a single char, then no long name, and remaining
* columns shift left (this becomes the short name)
* 3. option short name (single character name)
* if '-' or absent then no short name
* if neither long nor short name, line is ignored
* 4. option set short name (name of option equiv class)
* if '-' or absent then no class
* 5. default value of option
* if absent, default is 0
* only 0 or 1 possible (0==off 1==on) ("on" and "off" can be used)
*
* Data may be followed by any C preprocessor #if expression (incl the #if..)
* (including #ifdef #ifndef) to conditionalise output for that option.
* The #if expression continues until \n or next following '#'
