pkg-config --validate doesn't moan about multi-line description

Description

$ cat foo.pc Name: foo Description: An overly-long and pointlessly waffling description which has been line-wrapped URL: https://foo.example.org/ Version: 1.0 $ pkg-config --validate foo.pc && echo OK OK $ pkg-config --version 0.29

The documentation says:

   Files have two kinds of line: keyword lines start with a keyword plus a
   colon,  and variable definitions start with an alphanumeric string plus
   an equals sign.

So the wrapped part of the Description on line 3 should really be reported as an invalid line.
