upgrade: display the list of processed revlog before proceeding
This help to make sure we don't wrongly skip some in the test and to make sure
the user is aware of the amount of processing they is signing up for.

Check that config of the source repository is also loaded
$ hg showconfig ui.curses
[1]
$ echo "[ui]" >> ../source/.hg/hgrc
$ echo "curses=true" >> ../source/.hg/hgrc
$ hg showconfig ui.curses
true
Test that extensions of source repository are also loaded
$ hg debugextensions
share
$ hg extdiff -p echo
hg: unknown command 'extdiff'
'extdiff' is provided by the following extension:
extdiff command to allow external programs to compare revisions
(use 'hg help extensions' for information on enabling extensions)
[255]
$ echo "[extensions]" >> ../source/.hg/hgrc
$ echo "extdiff=" >> ../source/.hg/hgrc
$ hg debugextensions -R ../source
extdiff
share
$ hg extdiff -R ../source -p echo
BROKEN: the command below will not work if config of shared source is not loaded
on dispatch but debugextensions says that extension
is loaded
$ hg debugextensions
extdiff
share
$ hg extdiff -p echo
However, local .hg/hgrc should override the config set by share source
$ echo "[ui]" >> .hg/hgrc
$ echo "curses=false" >> .hg/hgrc
$ hg showconfig ui.curses
false
$ HGEDITOR=cat hg config --shared
