bug#17297: shell script gets weirdly indented inside case statement

[Stefan Monnier]

> Why the weird indenting for this shell script?

It's just that the tokenizer was confused with "do=", taken "do" for the
keyword used in "while foo; do bar; done" rather than
a variable identifier.  I installed the patch below which should fix it.
