[Rd] \value section for write_PACKAGES not updated

[Hervé Pagès]

Hi,

Found in \value section of man page for tools::write_PACKAGES:

   Invisibly returns the number of packages described in the resulting
   \file{PACKAGES} and \file{PACKAGES.gz} files.  If \code{0}, no
   packages were found and no files were written.

Those days (don't know when this has changed exactly), PACKAGES and
PACKAGES.gz are written, even if no packages were found (which is a
good thing BTW).

Thanks,
H.
