[R] list.files changed in 2.7.0

[davidr at rhotrading.com]

I just noticed a change in the behavior of list.files from 2.6.1pat to
2.7.0 
(I noticed it in 2.8.1 and traced back.)

Previously, if the directory ended with a slash, and full.names=TRUE,
the names 
returned had a single slash at the end of the directory,
but now there are two. I noticed since I was getting a list of certain
files and 
then grepping in the list for a full name formed with a single slash.
(The double slash would be OK if I were opening the file since the OS
treats double 
slash in a path the same as a single slash.)

I searched through the release notes, etc., and couldn't find this
announced.

Try
> list.files("C:", full.names=TRUE)
> list.files("C:/", full.names=TRUE)

Is there any chance that this could be put back to the single slash
behavior?

(This was on Windows XP.)

Thanks,
