gnome-doc-utils again

[Shaun McCance <shaunm gmail com>]

I've fixed more broken XML in gnome-doc-utils, this time in pt_BR.
There was this string:

<msgid>email.tooltip</msgid> <msgstr>Enviar e-mail para
<<node/>>.</msgstr>

It has those extra angle brackets, which are syntactically significant
to XML.  I'm assuming the intended effect was to wrap the email address
in angle brackets, so I changed it to this:

<msgid>email.tooltip</msgid> <msgstr>Enviar e-mail para
&lt;<node/>&gt;.</msgstr>

If I got it wrong, feel free to change it.
