extensions: call afterloaded() with loaded=False for disabled extensions If an extension was loaded but disabled due to a minimumhgversion check it will be present in the _extensions map, but set to None. The rest of the extensions code treats the extension as if it were not present in this case, but the afterloaded() function called the callback with loaded=True.

fetch: remove shorthand of --edit colliding against -e/-ssh in remoteopts (BC) Before this patch, -e/--edit and -e/--ssh of fetch command collide against each other. This causes that -e is treated as shorthand of --edit but doesn't work as same as --edit. Therefore, -e works as neither --edit nor --ssh, in practice. This issue was introduced at 595a69a01129 (or 1.0), which renamed -f/--force-editor to -e/--edit. At that point, -e was already used as shorthand of --ssh. After this patch, -e is treated as shorthand of --ssh. This patch is marked as "(BC)", because -e as shorthand of --edit in existing scripts causes failure (or unexpected result) after this patch. This impact should be less enough, because --edit mainly focuses on interactive use. BTW, test-duplicateoptions.py (since 7d171c05a631 or 1.9) can't detect this kind of issues as expected, because direct invocation of extensions.loadall() doesn't involve registration of commands defined in extensions (this issue is fixed in subsequent patch).

releasenotes: improve parsing around bullet points Earlier, on parsing the bullet points from existing release notes the bullet points after the first one weren't written correctly to the notes file. This patch makes changes to parsereleasenotesfromfile() function that introduces a new bullet_points data structure that tracks the bullets and associated subparagraph. It also makes necessary changes to the tests related to merging of bullets.

bookmarks: factor method _printer out of for loop in printbookmarks This allows even further customization via extensions for printing bookmarks. For example, in hg-git this would allow printing remote refs by just modifying the 'bmarks' parameter instead of reimplementing the old commands.bookmarks method. Furthermore, there is another benefit: now multiple extensions can chain their custom data to bookmark printing. Previously, an extension could have conflicting bookmark output due to which loaded first and overrode commands.bookmarks. Now they can all play nicely together.
