Ah, okay then.  I don't know why did I think it will make any
trouble.  Returning one slash less is okay, I think.

The only rule is that if some insane file name succeeds, so should
what you return.  And it shouldn't crash if the original one doesn't.

Sorry, I don't understand: will it work or not?

I was afraid that removing FOO from /dev/env/FOO will cause it to
fail, since /dev/env doesn't have a meaning without the variable
name.  And the same with /dev/c/foo.
