st: testing equivalence of long variable lists

I have some old code that uses this statement:

if "`tmp1'"=="`tmp2'" {

where tmp1 and tmp2 contain variable lists.  My understanding is that
if the variable list is longer than 244 characters, this will evaluate
to true if there is some difference between tmp1 and tmp2 after the
244th character.  Is this correct?  How does one test the equality of
long macros?
