%  Any coder prefix (EG: 'coder:filename') or read modifier postfix (EG:
%  'filename[...]') are ignored during the file the expansion, but will be
%  included in the final argument.  If no filename matching the meta-character
%  'glob' is found the original argument is returned.
%
%  For example, an argument of '*.gif[20x20]' will be replaced by the list
%    'abc.gif[20x20]',  'foobar.gif[20x20]',  'xyzzy.gif[20x20]'
%  if such filenames exist, (in the current directory in this case).
%
%  Meta-characters handled...
%     @    read a list of filenames (no further expansion performed)
%     ~    At start of filename expands to HOME environemtn variable
%     *    matches any string including an empty string
%     ?    matches by any single character
%
%  WARNING: filenames starting with '.' (hidden files in a UNIX file system)
%  will never be expanded.  Attempting to epand '.*' will produce no change.
%
%  Expansion is ignored for coders "label:" "caption:" "pango:" and "vid:".
%  Which provide their own '@' meta-character handling.
%
%  You can see the results of the expansion using "Configure" log events.
%
%  The returned list should be freed using  DestroyStringList().
%
%  However the strings in the original pointed to argv are not
%  freed  (TO BE CHECKED).  So a copy of the original pointer (and count)
%  should be kept separate if they need to be freed later.

%
%      status=ExpandFilenames(int *number_arguments,char ***arguments)
%
%  A description of each parameter follows:
