commitctx: document the manifest writing function

Same spirit as for `_filecommit` lets document the input and output before
making any change or improvement.

This is part of a larger refactoring/cleanup of the commitctx code to clarify
and augment the logic gathering metadata useful for copy tracing. The current
code is a tad too long and entangled to make such update easy. We start with
easy and small cleanup.

Test config default of various types:

 {"defaultvalue": ""} for -T'json(defaultvalue)' looks weird, but that's
 how the templater works. Unknown keywords are evaluated to "".

Test empty config source:

Test "%unset"

  $ hg showconfig unsettest

Test exit code when no config matches

  $ hg config Section.idontexist
  [1]

sub-options in [paths] aren't expanded

  $ cat > .hg/hgrc << EOF
  > [paths]
  > foo = ~/foo
  > foo:suboption = ~/foo
  > EOF

  $ hg showconfig paths
  paths.foo:suboption=~/foo
  paths.foo=$TESTTMP/foo

edit failure

  $ HGEDITOR=false hg config --edit
  abort: edit failed: false exited with status 1
  [255]

config affected by environment variables

  $ EDITOR=e1 VISUAL=e2 hg config --debug | grep 'ui\.editor'
  $VISUAL: ui.editor=e2

  $ VISUAL=e2 hg config --debug --config ui.editor=e3 | grep 'ui\.editor'
  --config: ui.editor=e3

  $ PAGER=p1 hg config --debug | grep 'pager\.pager'
  $PAGER: pager.pager=p1

  $ PAGER=p1 hg config --debug --config pager.pager=p2 | grep 'pager\.pager'
  --config: pager.pager=p2

verify that aliases are evaluated as well

  $ hg init aliastest
  $ cd aliastest
  $ cat > .hg/hgrc << EOF
  > [ui]
  > user = repo user
  > EOF
  $ touch index
  $ unset HGUSER
  $ hg ci -Am test
  adding index
  $ hg log --template '{author}\n'
  repo user
  $ cd ..

alias has lower priority

  $ hg init aliaspriority
  $ cd aliaspriority
  $ cat > .hg/hgrc << EOF
  > [ui]
  > user = alias user
  > username = repo user
  > EOF
  $ touch index
  $ unset HGUSER
  $ hg ci -Am test
  adding index
  $ hg log --template '{author}\n'
  repo user
  $ cd ..

configs should be read in lexicographical order

  $ mkdir configs
  $ for i in `$TESTDIR/seq.py 10 99`; do
  >    printf "[section]\nkey=$i" > configs/$i.rc
  > done
  $ HGRCPATH=configs hg config section.key
  99
