* function to create the context display...
*
* ("CONTEXT", instanceNum, contextLines, targetContextLine,
* contextLineLength, contextWordOffset, maxContextLinesSkipped,
* contextGutterWidth, ptrFileRefNum, textFileRefNum, subsetHandle)
* -- returns with contextLines of display followed by contextLines
* of instanceNum-textPtr pairs, with context instance instanceNum
* on line targetContextLine; if contextGutterWidth is non-zero,
* then that number of spaces are placed before the key word...
*
* function to empty out a subset so that no words are in the valid
* region:
*
* ("EMPTYSUBSET", subsetHandle)
* -- returns quietly with nothing if it successfully sets all bits
* in the subset flag array to zero; beeps and gives an error msg
* if it fails somehow...
