A strange behaviour of file.path in Windows? (PR#13119)

If you send these lines of code:

outdir="c:/pippo"
file.path(outdir,"pluto.html")

R replies correctly:

[1] "c:/pippo/pluto.html"

But if you change the first steps to:

outdir=""
file.path(outdir,"pluto.html")

R replies (uncorrectly, I think)

[1] "/c:/pippo/pluto.html"

I don't get the same output as you.  Are you sure you haven't changed 
output somewhere else in your code?

outdir="c:/pippo"
file.path(outdir,"pluto.html")

[1] "c:/pippo/pluto.html"

outdir=""
file.path(outdir,"pluto.html")

[1] "/pluto.html"

This is under R2.7.2/ Win XP.

Richie.
