```aggreed.tex point 16 (punctuation)

on the news group ``de.comp.tex'' there was a complaint, that `:=' and `=:'
do not look right, because the `:' is not centered to the math axis. There
was also some macro to raise the colon to right height (eek!).

How to solve this problem:
a) Correct the MF for `:' in math italic.
c) Do both a) and b)

After the whole discussion on mathord and mathrel I'm tending to b) rather a)
allthough it put two more symbol into the mathcore encoding.

As I am on this section, I disagree with Justin in the Notes 1 and 3. There
is no need in duplicating the punctuation symbols `.' and `:' in the font
encoding. Only one can be addressed intuitively via a \mathcode by typing
`.' resp. `:', the other must be addressed by a macro name anyhow. Let TeX
do the spacing.
