Patch to improve command-line parsing of tabs

[Brian Grayson]

  Here is a patch that improves command-line parsing
(WCMD_parse) -- it adds handling of tab as a parameter
delimiter in the same way that space is handled.  This is a fix
for my submitted Bug ID 2599, and was examined by one of the
Bug guys, who told me to forward the patch here.  The diff is
against 20041201.
