[Rd] GNU tar does not ignore files in .Rbuildignore (PR#1339)

[ripley@stats.ox.ac.uk]

This appears to be a bug in GNU tar 1.13 and not in R.  I can confirm it
for that version of tar on Solaris, but was aware that it went away when
the cygwin port moved to later versions.  All of 1.13.17 on Linux, 1.13.19
on cygwin and 1.13.25 (which I have just built on Solaris from
alpha.gnu.org) work correctly.  My memory is that 1.12 used to work, too.

Assuming info is finding the correct manual for 1.13, my reading of the
definition of exclude patterns is that build has it correct.

I don't like using alpha software in production work, but the lack of a GNU
tar release since 1999 makes this essential and it looks like all the
common Linux distributions supply later versions.
