'[' or test see the arguments after they are unquoted (normally).  So, 
if "$diffstat" is "-n" it might try and do the -n test, rather than the = 
test.

It could be re-written as "1" == "${diffstat}" instead to avoid the x, but 
it's not a big deal (to me).  That also looks backwards to a lot of people.
