hghave: list the module needed for the `vcr` check

I'm tired of having to look up modules each time I setup a system, and try to
distinguish between similar package names to get the right one.  Now that the
search API has been disabled, it's even harder.  There are other python packages
here that should be listed like this, but this is the one that came up missing
today, so it's a start.

Ignore file called "ignored"

  $ hg share main share
  updating working directory
  4 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg -R share tracked

  $ hg -R share files

Narrow the share and check that the main repo's working copy gets updated

# Make sure the files that are supposed to be known-clean get their timestamps set in the dirstate
  $ sleep 2
  $ hg -R main st
  $ hg -R main debugdirstate --no-dates
  n 644          2 set                 d1/f
  n 644          2 set                 d3/f
  n 644          2 set                 d5/f
  n 644          2 set                 d7/f
# Make d3/f dirty
  $ echo x >> main/d3/f
  $ echo y >> main/d3/g
  $ touch main/d3/ignored
  $ touch main/d3/untracked
  $ hg add main/d3/g
  $ hg -R main st
  M d3/f
  A d3/g
  ? d3/untracked
# Make d5/f not match the dirstate timestamp even though it's clean
  $ sleep 2
  $ hg -R main st
  M d3/f
  A d3/g
  ? d3/untracked
  $ hg -R main debugdirstate --no-dates
  n 644          2 set                 d1/f
  n 644          2 set                 d3/f

Widen the share and check that the main repo's working copy gets updated

  $ hg -R share tracked --addinclude d1 --addinclude d3 -q
  $ hg -R share tracked
  I path:d1
  I path:d3
  I path:d7
  $ hg -R share files
  share/d1/f
  share/d3/f
  share/d7/f
  $ hg -R main tracked
  I path:d1
  I path:d3
  I path:d7
  $ hg -R main files
  abort: working copy's narrowspec is stale
  (run 'hg tracked --update-working-copy')
  [255]
  $ hg -R main tracked --update-working-copy
# d1/f, d3/f should be back
  $ hg -R main files
  main/d1/f
  main/d3/f
  main/d7/f
# d3/f should be modified (not clobbered by the widening), and d3/g should be untracked
  $ hg -R main st --all
  M d3/f
  ? d3/g
  ? d3/untracked
  I d3/ignored
  C d1/f
  C d7/f

We should also be able to unshare without breaking everything:

  $ hg share main share-unshare
  updating working directory
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd share-unshare
  $ hg unshare
  $ hg verify
  checking changesets
  checking manifests
  checking directory manifests (tree !)
  crosschecking files in changesets and manifests
  checking files
  checked 11 changesets with 3 changes to 3 files
  $ cd ..

Dirstate should be left alone when upgrading from version of hg that didn't support narrow+share

  $ hg share main share-upgrade
  updating working directory
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd share-upgrade
  $ echo x >> d1/f
  $ echo y >> d3/g
  $ hg add d3/g
  $ hg rm d7/f
  $ hg st
  M d1/f
  A d3/g
  R d7/f
Make it look like a repo from before narrow+share was supported
  $ rm .hg/narrowspec.dirstate
  $ hg ci -Am test
  abort: working copy's narrowspec is stale
  (run 'hg tracked --update-working-copy')
  [255]
  $ hg tracked --update-working-copy
  $ hg st
  M d1/f
  A d3/g
  R d7/f
  $ cd ..
