hgweb: remove unused Graph() properties Both of these were introduced in 0dba955c2636, but were already unused.

gitweb: remove unused css classes Looks like they were unused since the very introduction of gitweb theme in 385b8872b8e3.

monoblue: also highlight target line on annotate and comparison pages Clicking on a line link on pages that show any kind of file contents (including diffs) should highlight that line, and in monoblue it works when there's a <pre> element (e.g. diff), but pages that use <table> element (annotate and compare) need this css class. It matches and highlights linked (":target") table rows. This line is pretty much copied from gitweb theme.

paper: remove css hack that made .branchname look like .branchhead There's a visual difference in hgweb between one changeset that is the tip of its branch and another that simply belongs to that branch. But paper theme ignored this difference on changeset page and used to always use "branchname" css class, be that changeset the tip of its branch or not. That has been recently fixed, so this piece of css is not needed anymore.

hgweb: rename the main attribute of instabilities Let's make "instabilities" list contain items with "instability" key as opposed to "name" key. This way it's more explicit and more consistent with the log command-line template.

hbisect: use a defaultdict to avoid large allocations for a large changelogs We can avoid a SPACE(len(changelog)) allocation by using a defaultdict. Test Plan: python run-tests.py test-bisect* Differential Revision: https://phab.mercurial-scm.org/D1499

hbisect: use a revset for ancestor calculation Since we have revsets we can be more concise in doing the ancestor calulcation. Significant commits are all descendent of the topmost good commits. Test Plan: python run-tests.py test-bisect* Differential Revision: https://phab.mercurial-scm.org/D1498

hbisect: pass repo into hbisect.bisect Pass repo into the bisect function to get more flexibility in what we can call. This will allow us to use revsets to rewrite parts of the ancestor and children calculation in later patches. Test Plan: python run-tests.py test-bisect* Differential Revision: https://phab.mercurial-scm.org/D1497

develwarn: do not emit warning if "config" is unspecified Previously, if the develwarn call site did not specify the category of warning, and devel.all-warnings was False, it would emit the warning. If it was intended that this emit a warning if config is unspecified, I would have expected a comment, so I assumed this was unintentional and am changing the behavior.

histedit: add support to output nodechanges using formatter The JSON output of nodechanges will help in automation and to improve editor integrations such as for Nuclide. Differential Revision: https://phab.mercurial-scm.org/D1348

rebase: use fm.formatlist() and fm.formatdict() to support user template Thanks to Yuya for suggesting this in D1173. Differential Revision: https://phab.mercurial-scm.org/D1293

tests: add test for rebase template showing wrong behavior The output for template "{nodechanges % '{key}:{value}'}" does not contain the output for value. Differential Revision: https://phab.mercurial-scm.org/D1462

remove: print message for each file in verbose mode only while using `-A` (BC) hg rm -A option prints the message of every file in the repo. This is not very user friendly for a big repository with thousands of files. So enabling this feature only when run in --verbose mode (hg rm -Av) Differential Revision: https://phab.mercurial-scm.org/D1336
