bug in 1.9b4 sdfopen and templating?

[Jennifer Adams]

Jamie, Hoop --
I vaguely remember making a small change to the templating code a long
time ago (for 1.9b1 perhaps) and I will take some time to go back and
look at whether my fix broke something else. In the meanwhile, I think
you can do what you want if you put the full path in the template
string as well as the filename string. In the sdfopen documentation, it
doesn't explicitly say that the path can be removed, it's just in the
example that it's done that way... perhaps it's just a documentation
problem. Try this:

ga-> sdfopen /Datasets/ncep.reanalysis.dailyavgs/pressure/hgt.2004.nc
Datasets/ncep.reanalysis.dailyavgs/pressure/hgt.%y4.nc 500'
