I've committed a change to r-patched to fix this in Windows only.
Sounds like it's not an issue elsewhere.

Gabor also suggested an option to use shell globbing instead of
regular expressions to select the files in the list, e.g.

list.files(dir="/", pattern="a*.dat", glob=T)

This would be easy to do in Windows, but from the little I know about
Unix programming, would not be so easy there, so I haven't done
anything about it.
