i18n space problem of consecutive {% trans %} blocks

[OmeletWithoutEgg]

In some languages (like zh_TW) we don't put spaces after periods, commas or between sentences. For example, 你好，世界。歡迎！ is correct but 你好， 世界。 歡迎！ is not.

It seems that some of CMS's i18n glues two sentences with a space, like:

cms/cms/server/contest/templates/overview.html

Lines 84 to 85 in 821fed5

	{% trans %}You can see the detailed result of a submission by using a token on it.{% endtrans %}
	{%+ trans %}Your score for each task will be the maximum among the tokened submissions and the last one.{% endtrans %}

or

cms/cms/server/contest/templates/overview.html

Lines 99 to 100 in 821fed5

	{% trans %}You have a set of tokens shared among all tasks.{% endtrans %}
	{{ contest|extract_token_params|format_token_rules }}

And it feels awkward to see those half-width space between two sentences in the translated pages.
