hg locate: inconsistent output

[Sanjoy Mahajan]

This output makes sense:

$ hg locate xyz
xyz: No such file or directory

But:

$ hg locate dsdt/600x.dsl
$ hg status dsdt/600x.dsl
? dsdt/600x.dsl
$ hg manifest | grep dsdt/600x.dsl

There is a dsdt/600x.dsl file and it is revision controlled, but it was
added in a different branch (in the same repository).

Shouldn't 'hg locate' complain (or not) equally in the two cases?  My
preference, following unix tradition, is for it to say nothing in either
case.
