[R-SIG-Mac] "Format" help when "DBI" package is loaded

[Parlamis Franklin]

Aqua GUI 1.13 (1930).
R 2.2.0

With DBI package loaded, when I type "format" in the spotlight help  
field below the toolbar, I get the help page for "print.list.pairs  
{DBI}".  If DBI is unloaded, I get the "format {base}" help page.

Problem does not occur when running R from Emacs in inferior-ESS  
mode, so I am pretty sure it is Aqua GUI-specific.
