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.

A fix with a single line results in a bullet point in the appropriate section

  $ touch fix1
  $ hg -q commit -A -l - << EOF
  > single line fix
  > 
  > .. fix::
  > 
  >    Simple fix with a single line content entry.
  > EOF

  $ hg releasenotes -r . $TESTTMP/relnotes-single-line

  $ cat $TESTTMP/relnotes-single-line
  Bug Fixes
  =========
  
  * Simple fix with a single line content entry.

A fix with multiple lines is handled correctly

  $ touch fix2
  $ hg -q commit -A -l - << EOF
  > multi line fix
  > 
  > .. fix::
  > 
  >    First line of fix entry.
  >    A line after it without a space.
  > 
  >    A new paragraph in the fix entry. And this is a really long line. It goes on for a while.
  >    And it wraps around to a new paragraph.
  > EOF

  $ hg releasenotes -r . $TESTTMP/relnotes-multi-line
  $ cat $TESTTMP/relnotes-multi-line
  Bug Fixes
  =========
  
  * First line of fix entry. A line after it without a space.
  
    A new paragraph in the fix entry. And this is a really long line. It goes on
    for a while. And it wraps around to a new paragraph.

A release note with a title results in a sub-section being written

  $ touch fix3
  $ hg -q commit -A -l - << EOF
  > fix with title
  > 
  > .. fix:: Fix Title
  > 
  >    First line of fix with title.
  > 
  >    Another paragraph of fix with title. But this is a paragraph
  >    with multiple lines.

  $ hg releasenotes -r . $TESTTMP/relnotes-fix-with-title
  $ cat $TESTTMP/relnotes-fix-with-title
  Bug Fixes
  =========
  
  Fix Title
  ---------
  
  First line of fix with title.
  
  Another paragraph of fix with title. But this is a paragraph with multiple
  lines.

Formatting of multiple bullet points works

  $ hg init multiple-bullets
  $ cd multiple-bullets
  $ touch fix1
  $ hg -q commit -A -l - << EOF
  > commit 1
  > 
  > .. fix::
  > 
  >    first fix
  > EOF

  $ touch fix2
  $ hg -q commit -A -l - << EOF
  > commit 2
  > 
  > .. fix::

  >    second fix
  > 
  >    Second paragraph of second fix.
  > EOF

  $ touch fix3
  $ hg -q commit -A -l - << EOF
  > commit 3

  > EOF

  $ hg releasenotes -r 'all()' $TESTTMP/relnotes-multiple-bullets
  $ cat $TESTTMP/relnotes-multiple-bullets
  Bug Fixes
  =========
  
  * first fix

Formatting of multiple sections works

  $ hg init multiple-sections

  $ touch fix1
  $ hg -q commit -A -l - << EOF

Section with subsections and bullets

  $ hg init multiple-subsections

  > .. fix:: Title of First Fix
