replaces translated help strings

[Wagner Bruna]

Since hgsubversion appends a paragraph to the doc string for some commands, their help texts are no longer translated by gettext.

Unfortunately, the translation system doesn't support additions to the doc strings. The attached patch simply disables the addition for translated strings.

I'm afraid I won't take this patch - I'm open to better solutions, but fundamentally, we need a way to add the documentation to hg's internal commands.

On Mercurial 1.6, the "_" function splits each message in paragraphs before translation, so the whole message isn't replaced anymore.

The last paragraph usually ends with four spaces, so it's still untranslated, but this can be fixed on Mercurial side.
