Hello Ralf,
Quite some time ago I had submitted a contribution to have mark
environment and mark section commands for Texinfo also. I made an update
of AUCTeX recently and I realized that they are still not in the CVS
tree...
I attach again the patch made at that time, but certainly the diff was
relative to some outdated version of tex-info.el.
Sorry, but I do not remember what was the outcome of discussion that we
had at that time. I rememeber that you questionned the use of `C-c .'
and `C-c *' keybindings, but I thought that my contribution was fine all
the same because no alternative keybinding was proposed.
VBR,
Vincent.
PS: The assignment was `Belaïche RT: 463852' of 2009-12-03, so from a
legal point of view I did it through.
