configitems: register the 'committemplate' section

configitems: register the 'color' section

configitems: register the 'alias' section

configitems: allow for the registration of "generic" config item Some section can contains arbitrary keys (eg: color, alias, extensions). We add a way to register some generic config items for them. This is necessary to get all the config registered. We use a regular expression because some sub- attributes (eg: hooks.xxx.priority) can define default value on their own.

transaction-summary: show the range of new revisions upon pull/unbundle (BC) Upon pull or unbundle, we display a message with the range of new revisions fetched. This revision range could readily be used after a pull to look out what's new with 'hg log'. The algorithm takes care of filtering "obsolete" revisions that might be present in transaction's "changes" but should not be displayed to the end user.

i18n: cache translated messages per encoding This is a simpler workaround alternative to D958, "i18n: clean msgcache when encoding changes." The cache won't be bloated unless you run tons of commands with different --encoding options on command server, or serve many repositories of different web.encoding options on hgweb. The test was originally written by Jun Wu. Differential Revision: https://phab.mercurial-scm.org/D1053

templater: fix ifcontains() to handle type mismatch gracefully This was unintentionally changed in ee0d74083a22. Since ifcontains() takes needle of any types, it shouldn't abort depending on the given container type.
