My bash highlighter thinks this is invalid. So does my brain. However 
bash seems OK with it. Why, I wonder? Maybe I am not clear on the 
expansion rules in this instance.

Ditto, except bash also (correctly IMO) doesn't like it.

That's odd, because all of the following are valid:

echo "'\""
echo `echo "'\""`
x="$(echo "'\"")" <-- this should be syntactically equivalent?!

...so this feels like a bug in bash.
