Bug#722539: mention random headers are generated

[jidanni at jidanni.org]

Package: perl-doc
Version: 5.18.1-3
Severity: wishlist
File: /usr/share/man/man1/perldoc.1.gz

       -f perlfunc
            The -f option followed by the name of a perl built-in function will extract the documentation of
            this function from perlfunc.

            Example:

                  perldoc -f sprintf

This should mention that it makes
2CKH0M1AL6(1) User Contributed Perl Documentation 2CKH0M1AL6(1)
random headers, else it looks like a bug.

Better yet would be saying
"Extract from PERLFUNC(1)" or something.
