httppeer: don't send empty Vary request header As part of writing test-http-bad-server.t, I noticed that some requests include an empty Vary HTTP request header. The Vary HTTP request header indicates which headers should be taken into account when determining if a cached response can be used. It also accepts the special value of "*". The previous code unconditionally added a Vary header. This could lead to an empty header value. While I don't believe this violates the HTTP spec, this is weird and just wastes bytes. So this patch changes behavior to only send a Vary header when it has a value. Some low-level wire protocol byte reporting tests changed. In some cases, the exact point of data termination changed. However, the behavior being tested - that clients react when the connection is closed in the middle of an HTTP request line or header - remains unchanged.

badserverext: explicitly flush each log write No idea why, but without this, there was no content in the error logs that are `cat`d in the test on Windows.

test-http-bad-server: conditionalize error output for Windows

test-tag: make hook runnable on Windows Simply setting the hook to *.sh causes Windows to open a dialog asking how to open *.sh files.

obsolescence: add test for the "branch replacement" logic during push, case D7 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. This changeset adds test for the improved "branch replacement" logic introduce in an earlier commits. This tests initially lived in the evolve extensions. Since we now have the code handling this logic in core, it make sense to have the tests in core too. See inline documentation for details about the test case added in this changeset.
