doheader function for EAPI 5?
A new "doheader" (and "newheader") helper function is on our list of
possible EAPI 5 features. It would be very easy to implement, just
copy the code from doconfd or doenvd.
However, this function was suggested in Bug 21310  which was filed
in 2003. The absence of any activity there makes me wonder if anybody
cares about the feature?
