Maybe we can just append a "v" check mark for correct syntax and "x" for
incorrect syntax? Hopefully GTK+ provides stock items for this.

essibility

"Accessibility means enabling people with disabilities of some kind to
participate in life's activities: in this case, specifically to use your
software. For example:

    o  Color-blind users may not be able to use your application if you
       rely only on color-coding to distinguish different types of
       information"

although, in this case, it's not distinguishing different types of
information, it's only providing a hint whose loss probably isn't fatal
- after all, it was arguably not really a hint to people using that
feature before the message to which I'm replying arrived, as I noticed
the background coloring but had no clue what it was telling me.)
