This is a characteristic of libxmls html parser.
The parser has a built in "knowledge" about allowed structures and adds
paragraphes if it finds content in contexts where it "thinks" they were
required.
It might be considered a bug, that the paragraph is not inserted before
the first <a>-element in your second example (the p insertion seems to 
be triggered by PCDATA content and not by inline elements like <a>,
which is not to consequent). 
OTOH tag soup parsing is always a mess...
And there no way do guess the right behaviour for user created elements
like gsweb.

Apart from modifying libxml, there is AFAIK no way of preventing the
<p> addition in the html parser.

HTH, greetings
