hgwebdir: avoid redundant repo and directory entries when 'web.name' is set
Previously, when 'web.name' was set on a subrepo parent and 'web.collapse=True',
the parent repo would show in the list with the configured 'web.name', and a
directory with the parent repo's filesystem name (with a trailing slash) would
also appear. The subrepo(s) would unexpectedly be excluded from the list of
repositories. Clicking the directory entry would go right to the repo page.
Now both the parent and the subrepos show up, without the additional directory
entry.
The configured hgweb paths used '**' for finding the repos in this scenario.
A couple of notes about the tests:
- The area where the subrepo was added has a comment that it tests subrepos,
though none previously existed there. One now does.
- The 'web.descend' option is required for collapse to work. I'm not sure what
the previous expectations were for the test. Nothing changed with it set,
prior to adding the code in this patch. It is however required for this test.
- The only output changes are for the hyperlinks, obviously because of the
'web.name' parameter.
- Without this code change, there would be an additional diff:

Test repositories inside intermediate directories
I'm not sure why the fancy name doesn't come out, but it is enough to
demonstrate that the parent is not listed redundantly, and the subrepo isn't
skipped.

'''browse command output with an external pager
To set the pager that should be used, set the application variable::
[pager]
pager = less -FRX
If no pager is set, the pager extensions uses the environment variable
$PAGER. If neither pager.pager, nor $PAGER is set, no pager is used.
You can disable the pager for certain commands by adding them to the
pager.ignore list::
[pager]
ignore = version, help, update
You can also enable the pager only for certain commands using
pager.attend. Below is the default list of commands to be paged::
[pager]
attend = annotate, cat, diff, export, glog, log, qdiff
Setting pager.attend to an empty value will cause all commands to be
paged.
If pager.attend is present, pager.ignore will be ignored.
Lastly, you can enable and disable paging for individual commands with
the attend-<command> option. This setting takes precedence over
existing attend and ignore options and defaults::
[pager]
attend-cat = false
To ignore global commands like :hg:`version` or :hg:`help`, you have
to specify them in your user configuration file.
The --pager=... option can also be used to control when the pager is
used. Use a boolean value like yes, no, on, off, or use auto for
normal behavior.
