New translations

[ABX]

Hi!

Probably too late for 2.7.2 but I'm posting it for considerations.

I worry about quality of our translations efforts. Preparing new translations
after recent update I noticed quite a lot of strings which probably do not need
translations at all. Some examples:

  xxxx
  2
  +
  )
  *
  ~

Also there is _("1.5") which in ideal world probably should consider comma
separator taken from locales.

Moreover some of translations starts and/or ends with spaces which are sometimes
'invisible' doing translation and finally translated strings do not really fit
the meaning.

HTH,
