doc: prevent non-literal text block from being treated as literal one This creates hg.1.html as expected.

histedit: show correct hash ID at verification error node.short() on 'ha' in verifyactions() causes broken hash ID, because it is initialized with node.hex()-ed node value.

backout: disable --merge with --no-commit (issue4874) Because "backout --merge" have to make a commit before merging, it doesn't work with --no-commit. We could change "backout --merge" to make a merge commit automatically, and --no-commit to bypass a merge commit, but that change would be undesirable because: a) it's hard to fix bad merges in general b) two commits would be created with the same --message So, this patch simply disables "--merge --no-commit".

changegroup: fix pulling to treemanifest repo from flat repo (issue5066) In c0f11347b107 (changegroup: don't support versions 01 and 02 with treemanifests, 2016-01-19), I stopped supporting use of cg1 and cg2 with treemanifest repos. What I had not considered was that it's perfectly safe to pull *to* a treemanifest repo using any changegroup version. As reported in issue5066, I therefore broke pull from old repos into a treemanifest repo. It was not covered by the test case, because that pulled from a local repo while enabling treemanifests, which enabled treemanifests on the source repo as well. After switching to pulling via HTTP, it breaks. Fix by splitting up changegroup.supportedversions() into supportedincomingversions() and supportedoutgoingversions().

tests: minor cleanup to treemanifest test

merge: don't try to merge subrepos twice (issue4988) In my patch series ending with rev 25e4b2f000c5 I switched most change/delete conflicts to be handled at the resolve layer. .hgsubstate was the one file that we weren't able to handle, so we kept the old code path around for it. The old code path added .hgsubstate to one of the other lists as the user specifies, including possibly the 'g' list. Now since we did this check after converting the actions from being keyed by file to being keyed by action type, there was nothing that actually removed .hgsubstate from the 'cd' or 'dc' lists. This meant that the file would eventually make its way into the 'mergeactions' list, now freshly augmented with 'cd' and 'dc' actions. We call subrepo.submerge for both 'g' actions and merge actions. This means that if the resolution to an .hgsubstate change/delete conflict was to add it to the 'g' list, subrepo.submerge would be called twice. It turns out that this doesn't cause any adverse effects on Linux due to caching, but apparently breaks on other operating systems including Windows. The fix here moves this to before we convert the actions over. This ensures that it .hgsubstate doesn't make its way into multiple lists. The real fix here is going to be: (1) move .hgsubstate conflict resolution into the resolve layer, and (2) use a real data structure for the actions rather than shuffling data around between lists and dictionaries: we need a hash (or prefix-based) index by file and a list index by action type. There's a very tiny behavior change here: collision detection on case-insensitive systems will happen after this is resolved, not before. I think this is the right change -- .hgsubstate could theoretically collide with other files -- but in any case it makes no practical difference. Thanks to Yuya Nishihara for investigating this.
