Hey,

Emacs' sh-mode when used for zsh scripts doesn't understand zsh's
alternate forms for complex commands[1]. This leads to the indentation
being completely wrong after using one such command. For example:

----------------------------------------
#!/bin/zsh

if [[ -z $1 ]] echo No args
   do_stuff Wrong indentation
----------------------------------------

The =C2=BBif=C2=AB ends on the same line it begins, therefore =C2=BBdo_stuf=
f=C2=AB should
not be indented at all.

Some more examples of what is wrong:

----------------------------------------
#!/bin/zsh

for arg ($@) echo argument $arg
    do_stuff Wrong indentation
----------------------------------------

or

----------------------------------------
#!/bin/zsh

while [[ -n $1 ]]; do
  if [[ $1 =3D=3D yes ]] echo oh yeah
     do_stuff Wrong indentation
----------------------------------------

Using { =E2=80=A6 } as the delimiters for the command list is not parsed
correctly either:

----------------------------------------
for arg ($@) { echo argument $arg ; cp $arg /backup/ ; }
    do_stuff Wrong indentation
----------------------------------------

and so on.

sh-mode is the original sh-script.el packaged with Emacs 24.4.1: 2.0f.
