This only happens after saving and reloading for me. I attached a patch that
constructs symbols with one and two spaces. As long as you don't save and
reload, the symbols stay intact even in message boxes. After saving and
reloading, they don't - they simply become message boxes containing ordinary
list rsp. meta messages with their elements separated by spaces like everywhere
else in Pd. Pd has no way to let these symbols survive saving, so if you need
them, you have to construct new ones each time. I guess, one could do a feature
request regarding this, but in the end the problem lies deeper and relates to
putting a proper string quoting and escaping mechanism in place.
