Another alternative is (untested)
\definemathcommand[dif][nolop]{\mfunction{d}\kern\zeropoint}

Roughtly, the above exapnds to
\define\dif{\mathop{\mfunction{d}}\nolimits}
When the argument of \mathop is a single character (d, in this case),
mathop centers the charater on the 'math-axis'. The rationale is that such
a behavior is desirable when defining single letter math operators such as
sum, int, bigcap, bigcup, etc. Adding \kern\zeropoint makes TeX think that
the argument of \mathop is more than a single character, so it does not
center d along the math-axis.
