Hello,

The target in *Windows classes is to mimic the old fashion CMD masks, 
and CMD masks does not have ranges or sets.

When I implemented that fnuction the code does not allow disabling 
features, so now that code can be changed to disable ranges, sets and 
escape char instead escaping the chars.

LCL's TMask raises syntax errors (or others, I can not recall) at 
creation time and in my code the syntax check is at Compile time so I 
call compile to raise an exception if needed. There is no performance 
loss as Compile should not be called again unless the mask is changed 
via the property.
