Bug report

Bug summary

Mathtext operators (\log, \max, etc.) should insert a thin space after themselves (if followed by ordinary characters, not if followed by an open parenthesis, see https://tex.stackexchange.com/questions/225922/spacing-rules-for-operatorname/225924#225924), but currently it does not.

Code for reproduction

from pylab import *
figtext(.5, .6, r"$\log 6$ (usetex)", usetex=True)
figtext(.5, .5, r"$\log 6$ (current)")
figtext(.5, .4, r"$\mathdefault{log}\,6$ (manual thin space)")
figtext(.5, .3, r"$\mathdefault{log}\ 6$ (manual full space)")
show()

Actual outcome

Note the missing thin space between "g" and "6" in the current behavior.

   Labeled this as hard because the fix is going to involve diving into the tex parser in https://github.com/matplotlib/matplotlib/blob/master/lib/matplotlib/mathtext.py but good first issue because there is no API design and should not require any changes outside of the mathtext.py.

   Is this done since #17890 was merged?

   I think sub/superscript handling is still a problem (#17890 (comment)).
