Comment 2 for bug 292025

I can reproduce the case with spaces:
irc_extra_hilight = foo bar

<CaioAlonso> foo [gets highlighted, not expected]
<CaioAlonso> bar [gets highlighted, not expected]
<CaioAlonso> foo bar [gets highlighted, expected]

Also, I can also reproduce the problem with words preceded by !@#$%*()_+, but there's a peculiarity:
if I use
irc_extra_hilight = !foo, !bar
then it works, but with
irc_extra_hilight = !foo
it doesn't work.
