Well, many routines the linear algebra section append a "2" when the 
routine does the same thing but using a different method/algorithm, so I 
was trying to be consistent with the naming, and I tried to document 
this routine thoroughly in the manual. I will think some more about 
whether it would make sense to make a longer descriptive name.

This was originally done since the code was based on the CSparse 
library, which did the same thing. You're probably right it makes sense 
to do more strict checking...although this code has been through a few 
releases so people's programs might break if we change the behavior now.
