Thanks a lot for having a look a this patch, and improving it.
The updated version did not work, though, but the fix was easy.
I do not understand why you have removed the num_commands stuff, which
indeed is not very useful but could be for debugging. No big deal.

Ok.

It needed some fixing. I understood that you suggest to avoid keeping the
last index and prefer the number of elements instead, so I applied it to
the Command struct as well.

Indeed.

Ok. Note that it is not a variable name but a prefix, so I named it
"prefix".

Ok.

Yep. I guess I did it 1 by 1 because it should be a rare case and it was
saving a counter. I've done some exponential thing instead.

I do not understand, the very same explanation text about prefix appears
in both entry? The examples are different, is that what you mean? They are
about different backslash commands, so they have an interest of their own.
Attached a v26 with I hope everything ok, but for the documentation that
I'm unsure how to improve.
