Need space before smiley

[kjell]

Hi all !

I don't want smilies in posts unless there is a space in front of the smiley code. I first tried to add the space in the ACP to every smiley but it seems like it's ignored so I guess it's removed by default.
Then I had a look in functions_bbcodeparse.php under the PARSE SMILIES section and tried to add a space in the replace function but neither did that help.

Can someone guide me where to change so only smilies with space in front will actually parse and shows up as icons in the posts.

Thanks in advance for any input.
