Hi,

I have a question about \doframedparentparameter from pack-rul.mkiv:

\def\doframedparentparameter#1#2{\ifx#1\relax\doframedrootparameter#2\else\doframedparameter#1{#2}\fi}

When the else branch is taken, it picks up the second argument, but
when the if branch is taken, it just picks up the first letter of
the argument (since the braces are missing). Is that intended? When
there are braces in the else branch there should also be braces in
the if branch.


normally #1 is a \cs and helpers like \doframedparentparameter are not 
user commands


(in the commandhandler variant {#1} is used but \framed is not yet using 
that code)

I was talking about the second argument #2. If #2 is always a
command, then you can write

\def\doframedparentparameter#1#2{\ifx#1\relax\doframedrootparameter#2\else\doframedparameter#1#2\fi}

if not, then

\def\doframedparentparameter#1#2{\ifx#1\relax\doframedrootparameter{#2}\else\doframedparameter#1{#2}\fi}

but the actual definition is neither of them, that is what confused me.
