--------------------------------
Summary: pattern [:space:] shortcut not matching as expected
Key: BIT-1497
URL: https://bro-tracker.atlassian.net/browse/BIT-1497
Project: Bro Issue Tracker
Issue Type: Problem
Components: Bro
Affects Versions: 2.4
Environment: Running tests using Bro 2.4.1 (precompiled from
http://download.opensuse.org/repositories/network:/bro/xUbuntu_14.10/) on
Ubuntu 14.10.
Running using a simple "/opt/bro/bin/bro myscript.bro" syntax.

I'm trying to do some RegEx-like pattern matching of a data stream using Bro,
and I'm finding that, at least some of the shortcuts, like '[:space:]' don't
seem to act as expected.
In short, I expected that '[:space:]' and '[ \f\n\r\t\v]' would be
interchangeable, but that doesn't seem to be the case. I have not tested any
other shortcuts like '[:alpha:]', '[:digit:]', etc. Just '[:space:]' so far.
I will attach an example script, as well as a file containing the output I'm
seeing.
