revset: cache smartset's min/max As the content of a smartset never changes, min and max will never change either. This will save us time when this function is called multiple times. This is relevant for issue4782 but does not fix it.

spelling: behaviour -> behavior

glossary: fixup use of periods at end of entries * Include trailing period for entries * Move trailing period inside quotations for example sentences

histedit: fix grammar for help for safety aborts

revset: mark reachablerootspure as private

reachableroots: construct and sort baseset in revset module This can remove the dependency from changelog to revset, which seems a bit awkward for me.

reachableroots: use smartset min smartset min are likely to be optimised, cached or other magical property.

graphmod: stop building a list out of branchgroupiter Not only does this defeat the purpose of having `branchgroupiter` an iterable, but this also makes revs something else than a smartset preventing to use revs.min() in the call to reachablerevs.

reachableroots: sort the smartset in the pure version too Changeset be8a4e0800d8 uses smartset lazy sorting for the C version. We need to apply the same to the pure version for consistency. This is fixing the tests with --pure.

builddeb: actually run make when building the deb (issue4778) As of this change, we no longer produce broken debs, but I've already got followups written that will produce much more standard-looking packages and test the resulting packages.
