zsh cygpath problem in cygwin

[Jan Lübbe]

Hello zsh users,

I have a very strange problem in cygwin. If I use cygpath normally in 
the zsh everything is fine. But if I assign a variable like JAVA_HOME 
then strange thinks happen. "k\b" disappears and stuff like that. The 
strange thing is, that this does not happen in bash under cygwin. It 
must somehow be related to the zsh. Do you have any ideas?

% JAVA_HOME="`cygpath -wl /cygdrive/d/Programme/Java/JavaEE61x32/jdk/bin`"
% echo $JAVA_HOME
D:\Programme\Java\JavaEE61x32\jdin
% cygpath -wl 
/cygdrive/d/Programme/Java/JavaEE61x32/jdk/bin/jboss-5.1.0.GA/bin
D:\Programme\Java\JavaEE61x32\jdk\bin

echo interprets escape sequences, you can use echo -E to suppress
this. The variable itself is correctly assigned. (\b means move the
cursor back one step, so this causes the i to overwrite the k.)

That is not a zsh problem or bug.  

The variable is getting set properly, it just that you can't print it out, because the display routine see's the backslashes, \'s, and treats it as an escape character, which means the next character is probably being turned into a non-printable control character.

N.B. for others "cygpath" is a command to translate windows pathnames to posix style names or other direction.

The below is not a full command? The argument is missing.
I suppose you meant --> cygpath -u "$JAVA_HOME"

Hope this helps.  The echo command willn ot output the results correctly, but
% cygpath -u "$JAVA_HOME"
will work and even the redundant

% cygpath -wl "$JAVA_HOME"
which will give you the same value.
