Yeah - sorry, I retyped rather than copying, and didn't realize the
difference it made until I'd already hit Send.
It always seems bizarre to me that that would be one of the characters
that needs escaping to have a special function in standard regex, and
consequently I always have trouble remembering it...
If it helps, they're both meta-characters. Logical notation embedded in a command stream. So both need to "escape" into logic from command-line reality :-)
