Sometimes it can be a problem when you can't type, say, asterisks
around a word when you NEED asterisks around the word, not a boldface
word (I'd been getting around it by using Unicode characters that look
like asterisks, like ∗). The way to do it right is to use the \ast
entity, which expands to the right thing but doesn't affect
formatting. There's also already a \tilde entity, to allow putting in
tildes without accidentally setting something verbatim. I added
entities for the remaining markup characters: \plus, \under, \equal,
and \slash. \under might be particularly handy when avoiding
subscripting (which raises the question of if there should be an
\asciicirc (or something) entity for ^ also).
I think they are all useful. Though, asciicirc already exists as circ.

I hadn't counted \circ because it expands under Unicode to ˆ (U+02C6) 
and not to the true ascii circumflex ^ (U+005E); the point of these 
entities is to represent ascii characters that otherwise would confuse 
things.  Maybe \circ should expand to ^; maybe there should be another 
entity for it (maybe neither).

Anyway; attaching the relevant patch (changelog tweaked), once again 
hoping I got the formatting and everything right.
