Dear Ralf,
The reason why there is this new variable is simply that I completely
missed the fact that this was already existing. I had looked only into
Texinfo, and I forgot to look out also in the native texinfo.
I provide hereinattached a corrected patch with a ChangeLog.
I also acknowledge the fact that there should be only one feature per
patch and not 3 like this:
1. optimization of texinfo-environment-regexp (use of regexp-opt)
2. Addition of environment mark function
3. Addition of section mark function.
I can split this into 3 differents/subsequent contributions with
respective ChangeLog -- or not, it is up to your feedback.
If you want 3 separate patches, then could you please tell me in which
order I should provide them.
BR,
Vincent.
PS: please remember I am not subscribed to the devel list, explicitely
include me for answer.
