context: possibly yield initial fctx in blockdescendants() If initial 'fctx' has changes in line range with respect to its parents, we yield it first. This makes 'followlines(..., descend=True)' consistent with 'descendants()' revset which yields the starting revision. We reuse one iteration of blockancestors() which does exactly what we want. In test-annotate.t, adjust 'startrev' in one case to cover the situation where the starting revision does not touch specified line range.

context: add an assertion checking linerange consistency in blockdescendants() If this assertion fails, this indicates a flaw in the algorithm. So fail fast instead of possibly producing wrong results. Also extend the target line range in test to catch a merge changeset with all its parents.

windows: add win32com.shell to demandimport ignore list Module 'appdirs' tries to import win32com.shell (and catch ImportError as an indication of failure) to check whether some further functionality should be implemented one or another way [1]. Of course, demandimport lets it down, so if we want appdirs to work we have to add it to demandimport's ignore list. The reason we want appdirs to work is becuase it is used by setuptools [2] to determine egg cache location. Only fairly recent versions of setuptools depend on this so people don't see this often.

obsolescence: add test for the "branch replacement" logic during push, case D6 Mercurial checks for the introduction of new heads on push. Evolution comes into play to detect if existing branches on the server are being replaced by some of the new one we push. The current code for this logic is very basic (eg: issue4354) and was poorly tested. We have a better implementation coming in the evolve extension fixing these issues and with more serious tests coverage. In the process of upstreaming this improved logic, we start with adding the test case that are already passing with the current implementation. Once they are all in, we'll upstream the better implementation and the extra test cases. See inline documentation for details about the test case added in this changeset.
