[SNIP; I cannot find any related bug report in the repository]

I'm just reviewing bug reports and other stuff re. legend() and found 
this old message in one of my Next-Week-To-Do-folders.

Well, the point mentioned above is not really a bug, because one has to 
specify BOTH arguments, angle AND density in legend(). Is there any 
point not to make angle = 45 the default, as it already is for polygon() 
and rect()?
