Hi list,

I'm studying org-block-regexp.  One thing that bugs me is this part:

#\\+begin_?

It suggests to me that the underscore after "begin" might be optional;
but a quick experiment with the exporter shows that this is not the
case.

Next, this part:

\\([^ \n]+\\)

would suggest that TAB is a valid part of the name of the block.
Strange, isn't it?

Finally, the rationale behind

\\(\\([^\n]+\\)\\)?

escapes me completely.  What's the use of groups nested like this?

Any ideas?

This is the case for dynamic blocks

  (info "(org) Dynamic blocks")

It is. "\\(\\S-+\\)" would be more appropriate I think (this is also
what is used in "org-element.el").

This looks like a plain bug, a minor one, tho. Before fixing it, Someone
has to make sure it doesn't break matching groups somewhere.
