It doesn't work when acroread is a wrapper script, which it is
in my case. (I used a wrapper instead of a symlink, because the
script needs to do some things before it starts acroread, such
as turning off core dumps (some versions of acroread 5.x used to
crash a _lot_).) Even if I rename the script to something other
than 'acroread', I still couldn't use =acroread since the real
acroread executable isn't in my PATH. :-/
So I'll just have to resolve the symlink using readlink. I assume
the most portable way to do this is perl, unless there is a way
to make zsh expand the link itself. I have attached a version that
does this. Should handle any level of symbolic links that point to
new symbolic links.
