templatekw: display active bookmark more consistently (issue4552) (BC)
Previously, the template keyword '{activebookmark}' would only display the
active bookmark if it was also pointing to the working directory's parent.
Meanwhile, the '{active}' subkeyword of the '{bookmarks}' keyword displays
the active bookmark regardless of whether it also points to the working
directory's parent. This is confusing.
Consider the output of these two templates:
$ hg log -T '{activebookmark}\n' -r indent
$ hg log -T '{bookmarks % "{bookmark}"}\n' -r indent
indent
This is the current behavior that can arise after, eg, a pull moves a bookmark
out from under you. After this patch, the first template will also return the
active bookmark that points to a revision, even if it is not the current
parent of the working directory. A test has been added to show the new behavior.
