namespace: introduce logfmt to show l10n-ed messages for hg log correctly

Before this patch, "_()" is used incorrectly for "tag:" and
"bookmark:" fields. "changeset_printer()" looks up keys composed at
runtime, and it prevents "xgettext" command from getting strings to be
translated from source files.

Then, *.po files merged with updated "hg.pot" lose msgids for "tag:"
and "bookmark:".

This patch introduces "logfmt" information into "namespace" to show
l10n-ed messages "hg log" (or "changeset_printer()") correctly.

For similarity to other namespaces, this patch specifies "logfmt" for
"branches" namespace, even though it isn't needed (branch information
is handled in "changeset_printer()" specially).

To find related code paths out easily, this patch adds "i18n: column
positioning ..."  comment to the line composing "logfmt" by default,
even though this line itself doesn't contain any strings to be
translated.
