Subject: [PATCH] Terminate standalone bracketed symbol strings

Standalone bracketed symbols like the following weren't being zero-terminated.

X EQUS {Y}

This doesn't apply to bracketed symbols that aren't standalone, but are
instead found in a string. For example, the following works even without this
fix.

X EQUS "{Y}"
