There are ways to ignore the spaces at the begin (\ignorespaces) and end (\removeunwantedspaces)
of a group but you should rethink first your interface for your commands (why no start/stop commands).
It can be also useful to draw the whole diagram with Metapost and use the TeX commands only
to pass the content to Metapost.
