The patch below makes a slight `improvement' to the CSH_JUNKIE_QUOTES
option. In order to emulate csh more accurately, this patch makes the
option prevent \ from quoting anything except a newline inside double
quotes. This makes zsh emulate csh behaviour fully w.r.t. single and
double quotes. Behaviour in backquoted expressions is still different,
but I suspect that that would be just too awkward to emulate fully.
This change is very simple.

\fBCSH_JUNKIE_QUOTES\fP
Complain if a quoted expression runs off the end of a line;
prevent quoted expressions from containing unescaped newlines.
+ (A backslash immediately preceding a newline in quotes escapes the newline.)
+ Also prevent backslash escaping anything other than newline in double quotes.
+ (Normally it would escape `\fB\e\fP', `\fB"\fP', `\fB$\fP' and `\fB`\fP'.)
+ This approximates

Just a note here. My releases emulate csh correctly in this respect even in
backquoted expressions sine about last march :-). But that was really the
smallest problem in the baseline lexer.
