copies-rust: implement PartialEqual manually

Now that we know that each (dest, rev) pair has at most a unique CopySource, we

Working-directory revision has special identifiers, though they are still
experimental:

  2147483647:ffffffffffffffffffffffffffffffffffffffff

  $ hg log -r 'wdir()' -T '{manifest}\n'

However, for negrev, we refuse to output anything (as well as for null)

  $ hg log -r 'wdir() + null' -T 'bla{negrev}nk\n'

Changectx-derived keywords are disabled within {manifest} as {node} changes:

  $ hg log -r0 -T 'outer:{p1node} {manifest % "inner:{p1node}"}\n'
  outer:0000000000000000000000000000000000000000 inner:

Check that {phase} works correctly on parents:

  $ cat << EOF > parentphase
  > changeset_debug = '{rev} ({phase}):{parents}\n'
  > parent = ' {rev} ({phase})'
  > EOF
  $ hg phase -r 5 --public
  $ hg phase -r 7 --secret --force
  $ hg log --debug -G --style ./parentphase

Test 'graphwidth' in 'hg log' on various topologies. The key here is that the
printed graphwidths 3, 5, 7, etc. should all line up in their respective
columns. We don't care about other aspects of the graph rendering here.

  $ hg init graphwidth
  $ cd graphwidth

  $ wrappabletext="a a a a a a a a a a a a"

  $ printf "first\n" > file
  $ hg add file
  $ hg commit -m "$wrappabletext"

  $ printf "first\nsecond\n" > file
  $ hg commit -m "$wrappabletext"

  $ hg checkout 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ printf "third\nfirst\n" > file
  $ hg commit -m "$wrappabletext"

The point of graphwidth is to allow wrapping that accounts for the space taken
by the graph.

  $ COLUMNS=10 hg log --graph -T "{fill(desc, termwidth - graphwidth)}"
  @  a a a a
  |  a a a a
  |  a a a a
  o    a a a
  |\   a a a
  | |  a a a

  |\ \   a a

Something tricky happens when there are elided nodes; the next drawn row of
edges can be more than one column wider, but the graph width only increases by
one column. The remaining columns are added in between the nodes.

  $ hg log --graph -T "{graphwidth}" -r "0|2|4|5"
  o    5
  |\
  | \
  | :\
  o : :  7
  :/ /
  : o  5
  :/
  o  3
