[R] ESS tab completion for file names

[Pascal A. Niklaus]

Hi all,

Using Xemacs/ESS (Xemacs 21.4-12/ESS 5.1.24), I noticed that tab 
completion does not work for file names.

df <- read.csv("xx     [TAB]

doesn't complete the file name.

After hitting TAB, I get "last thing matched was not a buffer" in the 
status bar. Any idea what may go wrong?

Thanks for any advice
