Close D1 bugs?

[Steven Schveighoffer]

I noticed Vladimir closed a D1 bug as WORKSFORME, with an explanation that  
it is fixed in the latest version of D2 phobos, not realizing it was a D1  
bug. (https://d.puremagic.com/issues/show_bug.cgi?id=1004)

However, it brought up a discussion of what to do with D1 bugs. Should  
they be closed? If so, what should be the reason for closing? My  
impression is if the bug still exists (and I'm not advocating we test for  
it), we should close it as WONTFIX, since D1 is deprecated.

Thoughts? I closed the aforementioned bug as WONTFIX. Anyone is free to  
correct that if you feel it's in error :)
