Thank you for the example. Syntax coloring is "working" for me in
the sense that I see colors, but the color of "[[" and "]]" seems
odd, the arguments to "print" aren't colored as they are if you
change "print" to "echo", and I would have expected "&&" to have
some color, but that seems inconsistent in the little bit of
experimenting that I did.

In any case, the top of $VIMRUNTIME/syntax/sh.vim shows that this
syntax highlighting script is maintained by Chip Campbell, who reads
this list regularly. I would expect some comment on this thread
from him by the end of today. If he doesn't see and reply to this,
then I would send your question to him directly at the address in
that file.

Regards,
Gary
