i18n space problem of consecutive {% trans %} blocks

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:
https://github.com/cms-dev/cms/blob/821fed553d419ef437bc00c208562a25ae060c1b/cms/server/contest/templates/overview.html#L84-L85

or
https://github.com/cms-dev/cms/blob/821fed553d419ef437bc00c208562a25ae060c1b/cms/server/contest/templates/overview.html#L99-L100

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

Start by inspecting the cited consecutive translation blocks in cms/server/contest/templates/overview.html and the related logic in cms/server/contest/formatting.py. Reproduce the rendered output for zh_TW and compare it with a language that uses spaces. Done means adjacent translated sentences no longer gain unwanted half-width spaces while spacing remains correct for languages that need it.
