n.b. In the following test case, you need an actual line-feed
char (C-q C-l) in place of the ^L

#!/bin/sh
var=^L
echo "this line gets indented"


If you auto-indent that script, the code following the line-feed
char is incorrectly indented.

I also see that the same thing happens with a carriage return char,
so maybe it's a white-space control character issue? (Space and Tab
don't trigger it, but I don't think those can be valid assignments
when they're not quoted.)

Other control chars don't seem to cause this.

Workarounds are quoting the LF/CR, or suffixing a semicolon.

Rather than LF/line-feed, I did of course mean FF/form-feed!

I shouldn't write bug reports whilst tired.

(Carriage return was correct, at least.)

So: the issue occurs with either a ^M or ^L character.

Apologies for any confusion. I've edited the subject and the
quote below to correct these mistakes.
