What I was trying to get at was the modules work like "if input file is
NULL, assume input comes from stdin". I don't think those modules actually
have code to deal with input=-, they will treat that as a filename not
something special. Some modules do recognize that trick, for consistency's
sake I suppose all that can read from stdin should, and if the parser
needs to be aware of that then so be it.
And AFAIK the parser does not actually check to see if an "old,file"
option's answer actually exists. It leaves that to the module. All it
provides is the folder file picker GUI. (Same is true for cell, vector,
group, ... elements) (??)
So the type isn't being dropped to accomodate 'oldfile=-', ->required is
being dropped to accomodate "if input file is NULL, assume input comes
from stdin".
not sure if we're talking about the same thing here...
