i18n: merge i18n comments of translatable texts correctly

Before this patch, i18n comments of translatable texts are lost at
creation of hg.pot file, if:

  - same translatable text appears multiple times,
  - the 1st appearance does not have i18n comment, and
  - any of rest has it

For example, previous patch for filemerge.py adds translatable texts
with i18n comments, but these comments are lost, because:

  - automatically added texts in docstring of internal merge tools are
    picked up earlier than these translatable texts, because of
    location in filemerge.py

  - but docstring has no i18n comment

This patch makes addentry() of posplit merge i18n comments of later
translatable texts, in order to keep them at creation of hg.pot.

If you can't run the entire testsuite for some reason (it can be
difficult on Windows), please at least run `contrib/check-code.py` on
any files you've modified and run `python contrib/check-commit` on any
commits you've made (for example, `python contrib/check-commit
273ce12ad8f1` will report some style violations on a very old commit).
