I noticed this in one of my documents, but it also seems to happen in your testsuite. See the units test. Here, the lines

\begin{displaymath}
\unit[1.1 \times 10^{-3}]{km}
\end{displaymath}

in units-old.tex and 

\begin{displaymath}
\unit[1 \times 10^{-3}]{km}
\end{displaymath}

in units-new.tex are converted into the diff

\begin{displaymath}
\DIFdelbegin %DIFDELCMD < \unit[1.1 \times 10^{-3}]{km}
%DIFDELCMD < %%%
\DIFdelend \DIFaddbegin \unit[1 \times 10^{-3}]{km}
\DIFaddend \end{displaymath}

which only shows the new value. Moreover, the new value is not marked as an addition (it is black instead of blue).
