I think so.

I got the same result.

Hmm...though I haven't yet looked into the actual code, current guess is
that the indent function `LaTeX-indent-line' doesn't like anything
immediately following \left\{. After I broke the line just after
\left\{, the result looked better:
\begin{equation}
  \label{eq:step-func:5}
  u(t-a) f(t-a)=\left\{
    \begin{array}{ll}
      0 & \text { if } t<a, \\
      f(t-a) & \text { if } t \geqq a .
    \end{array}\right.
\end{equation}
