Tweak the position of spaces between function invocations and arguments so that the expansion of mediawiki-specific functions (`\Rho`, etc) is consistent with how spacing is added to normal function invocations. This helps ensure that `texvc`/`texvccheck` is idempotent -- that is, that it can parse what it emits, and render it without change. Change-Id: I05fc8fa0201debf611ed4900d3cc953a6a8188ac
