We are finding the following situations in various HTML sources in the
web (mostly as a result of automatically generated HTML, e.g. man
pages), and, to put it mildly, it is confusing our browser and
ourselves....

... so quasi-authoritative answers (and corresponding cooperation from
HTML providers) to these questions would be greatly appreciated.

o What is the significance, if any, of <p>'s within a <pre> section?

o What is the significance, if any, of more than one <p> in a row,
  particularly on the same line?  And, how about the same situation in
  a <pre> section?

o Is '&lt' ('&lt;' without the semicolon) a valid construct?

o Can raw <'s and >'s be in a <pre> section?
