patch to set default for importing a .CSV file

["James R. Van Zandt" <jrv vanzandt mv com>]

I propose the following patch to appropriately set the defaults when
using file|import to read a .CSV file.

After putting this together, I discovered that file|open would read in
a CSV file without requiring any dialogs.  However, I didn't know
about that until just now, and I don't suppose every other user will
either.
