extdiff: don't run gui programs when in a cli-only environment In order to provide a useful error message to override the behavior, we also need to slightly change the way that tool.gui is found in the config. Before, it had to be where tool.diffargs is located, which might not exist. Now, tool.isgui can exist on its own. A test is added for the new error message. We also need to force procutil.isgui() to return true, so we set $DISPLAY to a non-empty value before running any test expecting to have a gui.

== New Features ==
* Windows will process hgrc files in %PROGRAMDATA%\Mercurial\hgrc.d.
== New Experimental Features ==
== Bug Fixes ==
* The `indent()` template function was documented to not indent empty lines,
but it still indented the first line even if it was empty. It no longer does
that.
== Backwards Compatibility Changes ==
== Internal API Changes ==
* Matcher instances no longer have a `explicitdir` property. Consider
rewriting your code to use `repo.wvfs.isdir()` and/or
`ctx.hasdir()` instead. Also, the `traversedir` property is now
also called when only `explicitdir` used to be called. That may
mean that you can simply remove the use of `explicitdir` if you
were already using `traversedir`.
* The `revlog.nodemap` object have been merged into the `revlog.index` object.
* `n in revlog.nodemap` becomes `revlog.index.has_node(n)`,
* `revlog.nodemap[n]` becomes `revlog.index.rev(n)`,
* `revlog.nodemap.get(n)` becomes `revlog.index.get_rev(n)`.
* `copies.duplicatecopies()` was renamed to
`copies.graftcopies()`. Its arguments changed from revision numbers
to context objects. It also lost its `repo` and `skip` arguments
(they should no longer be needed).
