listkey: display the size of the listkey payload in a debug message This is a useful information to have in general and we already have debug output related to listkeys. I'm planning to play around with massive amount of phases roots and bookmarks so having this data in debug will be very useful. This already got me to spot that one of the Logilab's review repo is exchanging 65KB of phases data during each exchanges.

basic test for hg debugrebuildstate

  $ hg init repo
  $ cd repo

  $ touch foo bar
  $ hg ci -Am 'add foo bar'
  adding bar
  adding foo

  $ touch baz
  $ hg add baz
  $ hg rm bar

  $ hg debugrebuildstate

state dump after

  $ hg debugstate --nodates | sort
  n 644         -1 set                 bar
  n 644         -1 set                 foo

status

  $ hg st -A
  ! bar
  ? baz
  C foo

  $ cd ..
