Bug-Description:
Roman Rakus dbeb5d
Roman Rakus dbeb5d 
bash40-024 introduced a regression for constructs like **/*.cs; that
Roman Rakus dbeb5d 
expansion would no longer include matching files in the current directory.
Roman Rakus dbeb5d 
This patch undoes portions of bash40-024 and fixes the original problem
Roman Rakus dbeb5d 
in a different way.
