Subject: 25.0.91; sh-mode indentation bug following LF/CR char variable assignments

From: Phil Sainty <[email-masked]>

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.
