Nitpick, the above is the source representation of a string intended to
be used as a regexp. The actual string (regexp) that this represents is:
\(\s-*\[\-\] \)\(.*\)
> (message regexp-display-string)
The first argument to `message` should virtually *always* be an
immediate string rather than a reference to a variable or some
computed value.
IOW, always do
(message "<blabla>" regexp-display-string)
unless you *really* know what you're doing and why you're doing it.
