changelog: document the 'readpending' method

I happen to have spent some time understanding this logic, so I'm leaving
documentation for the next poor fellow.

#require killdaemons

Tests discovery against servers without getbundle support:

  $ CAP="getbundle bundle2"
  $ . "$TESTDIR/notcapable"
  $ cat >> $HGRCPATH <<EOF
  > [ui]
  > logtemplate="{rev} {node|short}: {desc} {branches}\n"
  > EOF

Setup HTTP server control:

  $ remote=http://localhost:$HGPORT/
  $ export remote
  $ tstart() {
  >   echo '[web]' > $1/.hg/hgrc
  >   echo 'push_ssl = false' >> $1/.hg/hgrc
  >   echo 'allow_push = *' >> $1/.hg/hgrc
  >   hg serve -R $1 -p $HGPORT -d --pid-file=hg.pid -A access.log -E errors.log
  >   cat hg.pid >> $DAEMON_PIDS
  > }
  $ tstop() {
  >   killdaemons.py
  >   [ "$1" ] && cut -d' ' -f6- access.log && cat errors.log
  >   rm access.log errors.log
  > }
