Configuration file item to exclude characters from word selection

[GoogleCodeExporter]

I'd like to request a way to exclude certain characters from word selection 
when double-clicking.

The already exists WordChars to add characters, a configuration item to 
excluded characters would be nice too.

For example in the in-house language we use, % is used quite a lot for exmaple, 
%VLAUE1%, and I would like to be able to tell mintty to only select VALUE1 when 
I double-click.
