You are correct: now fixed in R-patched and R-devel.
I have fixed this once before, so that fix must have got lost.
BTW, the sources have an explanatory comment you don't see by listing the
function in R: it is necessary to set m$na.action explicitly because
match.call only includes supplied arguments, not default ones.
So the lines now reads
m$na.action <- na.action # force in even if default
