8 ** Bob Stout & Jon Guthrie
9 ** General cleanup, use NUL (in SNIPTYPE.H) instead of NULL where appropriate.
10 ** Allow spaces in tag names.
11 ** Allow strings in quotes.
12 ** Allow trailing comments.
13 ** Allow embedded comment separator(s) in quoted strings.
14 ** Add comments.
15 ** ReadCfg() now returns the number of variables found if no error occurred.
16 ** Changed integer type to short.
17 ** Use cant() calls in lieu of fopen() calls,
18 ** include ERRORS.H for prototype.
19 ** Fix parsing error with null string data.
