config: add a new [command-templates] section for templates defined by hg The existing `[templates]` section lets the user define their own keys and then refer to them on the command line with `-T`. There are many cases where hg wants to use a user-defined template with a given name, such as `ui.logtemplate` and `ui.mergemarkertemplate`. This patch starts moving such configs in a common section by moving `ui.logtemplate` to `command-templates.log` (with an alias from the old name, of course).

i18n: fix coding tag unsupported by xgettext Running `make update-pot` currently fails with the following error: xgettext: mercurial/metadata.py:1: Unknown encoding "utf8". Proceeding with ASCII instead. xgettext: Non-ASCII string at mercurial/metadata.py:311.

py3: hggettext `itervalues()` is only available on Python 2. Since this script doesn't currently refer to the main Mercurial modules, and as a result doesn't have easy access to the `pycompat` module, I simply changed it to use `value()` instead. Although this allocates a list on Python 2, I'd consider that acceptable for a utility script; Mercurial doesn't have all _that_ many commands anyway.

repoview: only pin obsolete wdir parents while there are unresolved conflicts I noticed after doing an update from an obsolete revision with a dirty wdir that the obsolete commit stayed visible for no obvious reason. It was decided in 85b03b1e4715 not to clear mergestate once all of the conflicts were resolved, in order to allow re-resolving. Since the point of pinning the obsolete parents was to allow resolving in the first place (aaeccdb6e654), it makes sense to also gate it on whether or not there are any remaining files to resolve. This might result in pinning again if files are marked unresolved again, but that seems reasonable, given that it still solves the original issue. Note that this isn't purely cosmetic- pushing with a pinned obsolete revision is likely to cause complaints about pushing multiple heads or other unexpected errors. So the faster it comes out of that state, the better. Differential Revision: https://phab.mercurial-scm.org/D9248

url: do not continue HTTP authentication with user=None (issue6425) I initially thought this is a py3-compat bug of passwordmgr._writedebug(), but actually returning (None, str) pair is wrong at all. HTTP authentication would continue with user="None" in that case. Since registering a password of user=None should also be wrong, this patch simply adds early return.

ui: fix echo back of ui.prompt() to not concatenate None as bytes Spotted while writing tests for the issue6425. The default value may be None.
