<ahelp> should not be empty/self-closing element (<ahelp ../>)

f5fa46ed8626910d710fd535518ddf9e756f9356 already fixed (tried to) the
empty/self-closing ahelp tag, however <ahelp ..></ahelp> is merged to
<ahelp .. /> by "make translations", so po files ended up with the
self-closing form again. Surrounding a child/PCDATA with the tag solves
the problem.
