Improve CommentDlgView unit tests for Markdown and plain text support.
Review Request #6471 — Created Oct. 20, 2014 and discarded
Many of the unit tests for the comment dialog now check against both the
Markdown and plain text editors, for things like key bindings, state
synchronization, and defaults.While here, I renamed the checkbox and label for the comment dialog's
Markdown checkbox from "Edit as Markdown" to "Enable Markdown."
Comment dialog unit tests pass.
