Hi,
Thanks for taking a look.
Afaict, the only difference between blank and [ \t] are some weird
unicode characters.
It isn't clear to me which one should be preferable and in what
situation. I couldn't find any reference to this in any documentation of
Org syntax.
I've replaced all instances of blank with (any " \t") in this function
(that's the only instances in org.el).
The attached patch fixes the original issue.
Regards,
Sébastien Miquel

This looks wrong, but so does the current regexp. It should not be
`space' nor `blank', but [ \t] per Org syntax.
