Here are a few syntax features that I propose we deprecate for 1.5,
the reasons are mainly to simplify the the wikitext to make parsing
simpler.
1. <p>
The only reason one would want to use <p> is to avoid the effect two
newlines have of spawning a new paragraph, that is, to be able to
write something like:
<p>This
Is all one
Paragraph</p>
This feature is seldom (if ever) used.
2. <i> and <b>
We have a syntax for these two, namely ''' and '' for <b> and
<i> respectively.
3. {{msg:}}
Leftover stuff from the 1.2 days, let's kill it;)
