[Documentation] Strange math input

[dbitouze]

In beamerthemeexamplebase.tex, math formula "q + 1" is typeset with the strange input $q$\;+\,$1$. Why not simply $q+1$?

\documentclass{standalone}
\usepackage{mathtools}
\usepackage{amssymb}
\begin{document}
$q$\;+\,$1$

$q+1$
\end{document}

Guess this has something to do with #375.

Actually, the rationale is stated in beamerthemeexamplebase.tex:

The strange way of typesetting math is to minimize font usage in order to keep the file sizes of the examples small.

@SFr682k Indeed. But, @josephwright, is is still worth nowadays?

There's nothing actually wrong with it: I'm minded to leave alone

As shown by the screenshot, the spaces aren't the same with $q$\;+\,$1$ and with $q+1$.

The correct glues will be $q$\:+\:$1$.

This is ugly!
