Comment #3 on issue 2935 by [email protected]: Issue 2859 (Provide
\hide and \omit functions) breaks -dsafe option

I can confirm that the commit you suspected is actually the culprit.
I can also say that it is a critical regression. The commit causes a
function to fail in the current development version which does not fail in
the current stable version. That's the definition. For a while we also
called anything that prevents development proceeding critical - and this
does cause me the minor pain of being unable to update the docs from the
LSR.
