This says to use \ to release quotes. The 105 truncation attribute does
not list \" as something that can be released. (I think the 105 spec
should be clear what \ means when followed by one of the characters
not listed.)

The benefit of saying its an error to follow \ by anything other than
*, ?, +, |, and \ is that special meaning can be introduced later if
desired (such as \xhh or \ooo for hex or octal digits).

The benefit of saying \ releases whatever the following character
is, is simplicity.

I am not proposing anything - just pointing out a hole that would
impact any implementation that I did. I was also wondering if \"
should be added to the 105 spec if that is what CQL is using.
Implementable either way, but mildly easier to implement if \" is
allowed.
