Without hacking, is there a way to stop vB from applying nl2br() on my text?

[nick1presta]

I created custom BBCode for console output ([CLI][/CLI]).
However, the newlines are converted to <br /> which wouldn't pose a problem except that the division which holds the text inside the [CLI] tags has "whitespace: pre" applied to it so tabs and such are preserved. This means that all newlines are "double lines" because of the initial newline plus the <br />.

Without hacking the source, is there a way to stop the conversion of nl2br()?

Thanks in advance.
