[Plugin: RSS Footer] Percentage signs displayed in RSS feed using RSS footer plugin

I am using v0.9.1 of the RSS footer plugin, and I have my RSS footer set to:

%%POSTLINK%% is a post from: <a href="https://domain.com">My Site</a>

When viewing the RSS feed, POSTLINK is correctly changed to the post title/url, but there are still percentage signs around it.

I think there’s a bug in the plugin, and line 143 of the plugin should be changed from:

$rssfootcontent = str_replace("POSTLINK",$postlink,$rssfootcontent);

to:

$rssfootcontent = str_replace("%%POSTLINK%%",$postlink,$rssfootcontent);

Thanks very much.
