How does that make it not a regression?  The information used to be 
provided, now it isn't.

 From a user's perspective, I don't care what the implementation is. 
This *looks* broken.  Any user that relied on the information being 
present (which is a reasonable expectation given that the tool used to 
provide it and still attempts to) will consider this a regression.

I assert that expecting command lines for Cygwin processes to be 
viewable in tools like Windows Task Manager and SysInternals Process 
Explorer is a reasonable expectation - especially since they have been 
present there for many releases - again, going back to at least the 
1.5.x days.  This change may have been intentional, but from a user 
perspective, it has broken behavior that any Windows user would 
reasonably expect to be able to rely on.

Tom.
