templatekw: allow accessing to nested namespace item by its template name Since we have the dot operator, it makes more sense to write {namespaces.tags % "{tag}"} instead of {namespaces.tags % "{name}"}

templatekw: get rid of temporary dicts from shownamespaces()

templatekw: rename peerpaths to peerurls per naming convention (BC) Since each element is called as "url", the template keyword should be named as "<whatever>urls". {peerurls} is now stabilized.

templatekw: make experimental {peerpaths} return a single-level dict (BC) This was planned as in c0d8de2724ce, "{peerpaths.default.pushurl} will be translated to peerpaths['default'].makemap()['pushurl'], which means {peerpaths} should be a single-level dict and sub-options should be makemap()-ed."

templatekw: fix scope of peerpath url bound to generator I had to explicitly bind 'd' to the generator. Otherwise, the last 'd' would be used.

templater: extend dot operator as a short for get(dict, key)

templater: add dot operator to easily access a sub item This and the next patch will allow us to access a deeply-nested item by foo.bar.baz syntax.

templater: wrap get/min/max result so map operation can apply to element See the test for usage example. wraphybridvalue() takes a key/value pair because a hybrid dict passes a key to its makemap() function. Since makemap() of showmanifest() doesn't need a key, it's set to None.

dispatch: move initialization of sys.std* files I'll add another Python 3 hack.

chg: just forward --time to command server Since we've removed the use of atexit in de5c9d0e02ea, --time just works.

windows: add an experimental option for long paths support This commit adds an experimental --long-paths-support flag to build_hgexe on Windows. It is off by default, but when supplied, causes setup.py to embed some XML into the generated hg.exe, which in turn tells Windows to allow this exe to use long paths (given that the appropriate registry setting is enabled as well). This was tested on Windows 10 14393 and 15063. This commit introduces a badly-named initialize_options function, but its name is dictated by distutils, rather than chosen. # no-check-commit

configitems: register 'merge.checkunknown' and 'merge.checkignored' They both use the same function defining a default, so we need to update them at the same time.

configitems: register the 'diff.*' config All the config were already using a unified function with a forced default, so, registering them all at once seems safe.

copies: add docs for config `experimental.copytrace.sourcecommitlimit` This patch adds documentation for the config option. The config name does not convey much and hence documentation was required. Differential Revision: https://phab.mercurial-scm.org/D986
