            Bug ID: 1184662
           Summary: more bad requires generated by "use" in heredoc
           Product: Fedora
           Version: 21
         Component: perl-generators
          Severity: low

Description of problem:
Much like my old bug #198033, perl.req is finding the phrase "use for" at the
beginning of a line within a "print <<END" heredoc, and generating a
"perl(for)" requires which isn't satisfiable.

Version-Release number of selected component (if applicable):
perl-generators-1.00-1.fc21.noarch

How reproducible:
consistently

Steps to Reproduce:
1. get & prep pgp-tools-1.1.10-1.fc21.src.rpm (currently in testing)
2. rpmbuild -bb SPECS/pgp-tools.spec (or -ba)

Actual results:
requires perl(for)

Expected results:
does not require perl(for)

Additional info:
There's already a section to skip over some heredocs, but only ones following
an assignment '=', lines 86-96 in /usr/lib/rpm/perl.req. It should be pretty
simple to tweak that to at least allow it to work for heredocs following "echo"
& "print" as well. I'm not sure that there aren't other uses for "<<", but
maybe it would be for the best to just count it as heredoc opening regardless
of what comes before it on the line? If that leads to skipping all the rest of
the file in some cases, well, that would be a bad thing.
