> Components: Bro

> Environment: Running tests using Bro 2.4.1 (precompiled from http://download.opensuse.org/repositories/network:/bro/xUbuntu_14.10/) on Ubuntu 14.10.

> 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.
