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.

# genmerges is the workhorse of the test-merge-combination-*.t tests.
# Given:
# - a `range` function describing the possible values for file a
# - a `isgood` function to filter out uninteresting combination
# - a `createfile` function to actually write the values for file a on the
# filesystem
#
# it print a series of lines that look like: abcd C: output of -T {files}
# describing the file a at respectively the base, p2, p1, merge
# revision. "C" indicates that hg merge had conflicts.
