templatekw: make {latesttag} a hybrid list This maintains the previous behavior of expanding {latesttag} to a string containing all of the tags, joined by ':'. But now it also allows list type operations. I'm unsure if the plural handling is correct (i.e. it seems like it is usually "{foos % '{foo}'}"), but I guess we are stuck with this because the singular form previously existed.

templatekw: allow the caller of showlist() to specify the join() separator The keyword {latesttag} currently manually joins the list of tags using ':', which prevents a transparent switch over to a hybrid list.

archive: use {changessincelatesttag} to build the metadata file This isolates the current magic when dealing with wdir() and only().

templatekw: introduce the changessincelatesttag keyword Archive is putting a value with the same name in the metadata file, to count all of the changes not covered by the latest tag, instead of just along the longest path. It seems that this would be useful to have on the command line as well. It might be nice for the name to start with 'latesttag' so that it is grouped with the other tag keywords, but I can't think of a better name. The initial version of this counted a clean wdir() and '.' as the same value, and a dirty wdir() as the same value after it is committed. Yuya objected on the grounds of consistency [1]. Since revsets can be used to conditionally select a dirty wdir() or '.' when clean, I can build the version string I need and will defer to him on this.

help: support 'hg help template.somekeyword' Previously the output was simply 'abort: help section not found'.

hgweb: also monitor change to bookmarks This makes changes to bookmarks visible to hgweb through the official way. There is no change to tests because there is currently another hack in place to ensure the same behavior.

hgweb: also refresh the repo on changes to the obsstore Before this change, hgweb could miss update to the obsolescence markers store if that was the only change between two commands.

hgweb: use an extensible list of files to check for refresh The refresh feature was explicitly testing if '00changelog.i' and 'phaseroots' changed. This is overlooking other important information like bookmarks and obsstore (bookmark have their own hack to work around it). We move to a more extensible system with a list of files of interest that will be used to build the repo state. The system should probably move into a more central place so that the command server and other systems are able to use it. Extension writers will also be able to add entries to ensure that changes to extension data are properly detected. Also the current key (mtime, size) is notably weak for bookmarks and phases whose files can easily change content without effect on their size. Still, this patch seems like a valuable minimal first step.
