files: speed up `hg files` when no flags change display It's not the first time I see slowness from this command slow down tools built on top of hg. The majority of the time is spent merely printing the result before this change, which is clearly not how it should be (especially since the computation of the result also looks slow). Running `hg files` in mozilla-central: parent revision: 1,260s this commit: 0,683s this commit without batching ui.write: 0,931s this commit replacing the body of the loop with `pass`: 0,566s This looks like a prime candidate for a rust fast path, but until then, it seems reasonable to optimize the python.
