ITicketManipulator.validate_ticket() return values should be able to include markup

[Daniel Kahn Gillmor <dkg-debian.org@…>]

Since the error messages returned from validate_ticket() by implementations of ITicketManipulator are displayed to the user, it would be good if plugins providing that interface could return some form of markup in the error message.

For example, the error message:

You can't make that change because you are not part of the security team.

Might be better rendered as:

You can't make that change because you are not part of the security team?

But i can't find a way to do that in 0.11b1.

asked about this on IRC, coderanger suggested:

"it should probably be fixed to allow Markup() and genshi.builder elements"

Good idea. I'll put it on my to-do list.
