[O] Re: [Orgmode] IMPORTANT Modified link escaping in Org mode

[Michael Brand]

Hi David

The current version of dmaus/org-check-percent-escapes from Worg
http://orgmode.org/worg/org-hacks.html#check-old-link-escapes
loops forever in the outer while when used on a one line Org buffer
containing just [[http://www.orgmode.org]] except I hack something
like (goto-char end) behind the inner while. What am I doing wrong?
Did anybody else have this issue?

Michael
