copies: speed up copy detection On some large repos, copy detection could spend > 10min using fctx.ancestor() to determine if file revisions were actually related. Because ancestor must traverse history to the root to determine the GCA, it was doing a lot more work than necessary. With this replacement, same status -r a:b takes ~3 seconds.

hgweb: request: strip() form values Entering "<correct_cset_hash> " in the search form was not returning anything. This happens relatively often, due to HTML formatting: when copy/pasting a cset hash from the web, selection might contain surrounding spaces.

templatekw: fix extras, manifest and showlist args (issue1989) Removing the explicit parameters from keywords signature is easier than copying and reproducing the original argument list.

share: be more explicit about the dangers of rollback.

mercurial.spec: Alignment with AIX spec by Jim Hague * Require Python 2.4 or later * Note that hgk uses tk - but don't require it * Remove bashism to support ksh * Install mq.el * Handle uncompressed man pages

hgweb: changenav: separate pages before and after the current position This should allow styles to customize more precisely navigation bar, for example inserting a cursor to show where we are in the navigation bar.

Work around AIX shell builtin printf not handling \NNN. On AIX, ksh builtin printf does not understand \NNN. Some tests use this to generate test data, and so fail on AIX. Rework these tests to use python to generate the correct characters. This fixes the tests on AIX and should be more generally portable.

subrepo: fix merging of already merged subrepos (issue1986) This fixes a bug seen when merging a main repo which contains a subrepo when both repos have been merged before. Each repo (main and sub) has two branches, both of which have been merged before. In a subrepo, if the revision to merge to is an ancestor of the current rev, then the merge should be a noop. Test provided by Steve Losh.

cmdutil: hide child window created by win32 spawndetached() Hiding the child process window is not strictly necessary but it avoids opening an empty shell window when running hg serve as well as a task in the task bar. The window is hidden after the process is already started causing a single flicker.
