Taken from PR 199861, but update to 1.9.0.
As this PR is unanswered by kuriyama@ (like also a mail from me about rubygem-gettext and -locale) since weeks, I would commit this, once I get clearance here. I will need rouge >= 1.7 for jekyll 3 anyway...
Proposed commit message:
textproc/rubygem-rouge: update to 1.9.0 PR: 199861 Submitted by: Michael Fausten <email@example.com> Approved by: swills (mentor), mat (mentor), kuriyama (maintainer, timeout)
