Some issues with \unit

Some issues with \unit

Hi,

most of these issues already have been discussed last year¹, but
they don't seem to be solved, yet.

1) \unit{10^3} does display as 10✕10³. This is confusing and wrong.

2) Expressions like \unit{e3} result in ✕10³ instead of 10³. The
   multiplication sign should be dropped in this case.

3) The minus sign: \unit{e-3} It's too long. In math mode the
   correct character is used, but the spacing is messed up.

4) AFAIK there's not yet an interface to change the multiplication
   sign.

  \def\digitstimessymbol
    {\kern.2\emwidth\cdot\kern.2\emwidth}

Full example:

\starttext
  \unit{10^3 second}           \crlf %% ⇒ 10✕10³ s
  \unit{10^{-3} second}        \crlf %% wrong — sign, too long
  \math{\unit{10^{-3} second}} \crlf %% wrong spacing
  \unit{e3 second}             \crlf %% ⇒ ✕10³ s
\stoptext
