Revert "Fixes XML compilation error for `sl`"

There are a few more lines which end with a newline then this fix
targets.

This reverts commit 5ea41b13493af4376f07d4ee87b956a97cfaeab9.
Fixes XML compilation error for `sl`

This patches an error and failure compiling XML:

    po/sl/menus/colors/components.po:302: 'msgid' and 'msgstr' entries
    do not both end with '\n'

I've left the pair as fuzzy, since I know nothing of the slovenian
translation for HSL.
