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.

In this test, we want to test LFS bundle application on both LFS and non-LFS repos. To make it more interesting, the file revisions will contain hg filelog metadata ('\1\n'). The bundle will have 1 file revision overlapping with the destination repo. # rev 1 2 3 # repo: yes yes no # bundle: no (base) yes yes (deltabase: 2 if possible) It is interesting because rev 2 could have been stored as LFS in the repo, and non-LFS in the bundle; or vice-versa.
