I think there are some missing words in "R Internals"'s description of
the P_ macro.
It currently has "A macro as a wrapper for ngettext", which I think
ought to be
something like "The macro P_ may be used as a wrapper for ngettext".
The following patch also makes the 2 alternate definitions of P_ have
the same argument names,
StringS and StringP. Expanding the S and P to Singular and Plural,
would be more descriptive.
