topic: dedent items about publishing behavior in docstring Also change item bullets from '#' to '*'.

topic: use preformatted block for config snippets documentation We add :: markers, empty line and properly indent blocks where needed.

tests: add a test for "hg help -e topic" Currently, some configuration snippets do not render well; we'll fix this in forthcoming changesets.

branching: merge with stable

content-div: add test showing `--stop` works during interrupted resolution This patch adds a test showing that the --stop flag of `hg evolve` works well during interrupted content-divergence resolution. The --stop flag now works with all the three different type of instability resolution very well and we should advertise it more.

evolve: create new commit while resolving content-divergence Before this patch, we used to amend one of the content-divergent changes with the changes from the merge. Creating a new commit will certain advantages like letting user enter a commit message, showing user the new merge diff before commiting the content-divergent resolution and give us more control in the implementation part. The reason amend was used initially was just because it was easy. There are some tests update due to change.

content-divergence: store the resolved revs in evolvestate['replacements'] The support for continuing a conflicted content-divergence resolution was added some time ago. That support lacked storing of the resolved rev in the evolvestate['replacements'] which marks the node as resolved and does not try to resolve that node again. Since we didn't store, the resolution, processes the same node again. This patch makes sure we store the information in evolvestate that a certain content-divergent node is resolved to prevent pre-processing it again.

utility: use ui.interactive() instead of checking config value Before this patch, the rev selection prompt which pops up in case of ambiguity to ask user to select a rev used to check the config value of ui.interactive which can is by default set to None. We should use ui.interactive() instead which is more smart in such cases. Thanks to martinvonz for suggesting this.

evolve: make `--abort` strip the temporary revs created during resolution During divergence resolution, `hg evolve` created temporary relocation commits which needs to be stripped off during `hg evolve --abort` to get back to the same state where we were. Previous patch added a new list temprevs to be stored in evolvestate. This patch starts storing the temp relocated node created during phase-divergence resolution in evolvestate and make sure we consider stripping it too while `hg evolve --abort`. The test changes demonstrate the fix. Now we are sucessfully aborting a phase-divergence resolution.

evolve: store a list of temprevs in evolvestate There are temporary revisions which are created as a part of divergence resolution which needs to be stripped off if user runs `hg evolve --abort`. We need to save the nodeids of those temporary revisions in the evolvestate. The temprevs list will help in the above mentioned use cases.
