This was fixed in v1.21 of pg_autovacuum.c, That rev is tagged for
beta3, so you should not be seeing this issue unless you actually have
an older version for some reason.

It's not so much that it strips them (that happens automagically), more
that it doesn't re-add them when it writes the command line in the
registry. The attached patch fixes that by simply quoting all options
that may need it.

A -E <service> option is added in the attached patch.
