The properties parser in Silme ignores entities which beginns with spaces like " stateBlockedPolicy=This download has been blocked by your Security Zone Policy" in toolkit/locales/en-US/chrome/mozapps/downloads/downloads.properties. I think that we need to change this regexp: entityPattern = re.compile('^([^#!\s\r\n][^=:\r\n]*?)\s*[:=][ \t]*(.*?)[ \t]*$',re.M) to solve the problem.
Oh, sure. Please, take a look at Pike's regexp for properties and also make sure that your regexp covers multiline properties. Then give me a patch and we're done :)
thanks Gandalf :)
