I assume you mean to say "ado-file", not "do-file".
My approach, if you want the if/in and/or options parsing capability of
syntax, would be to use the "anything" argument of -syntax-, which
allows an arbitrary set of stuff where the varlist would normally go.
syntax anything [if] [in] , OPtion(string)
See -help syntax-
