Summary: Cannot change a string to one which has spaces in it.
Description:
I attempt to change a variable containing a string (the string is
arbitrary) using the property_set request to a string which contains
spaces, but it fails. I can change the string to anything else so long as
it has no spaces in it.

eg I have a string with the contents "Welcome to PHP", and I tried to
change it to "This is", but it is rejected. The command issued is

property_set -i 189 -n $b -d 0 -l 12 -- VGhpcyBpcw==

<?xml version="1.0" encoding="iso-8859-1"?>
<response command="property_set" transaction_id="189"
success="0"></response>

If I change it to "ThisIsI" then the command is
property_set -i 193 -n $b -d 0 -l 12 -- VGhpc0lzSQ==

<?xml version="1.0" encoding="iso-8859-1"?>
<response command="property_set" transaction_id="193"
success="1"></response>

I have checked that the base64 encoding decodes correctly to a string with
spaces.

Although property_set still needs some work, this is expected behavior.
Send the variable with quotes around it and it will work just fine.
Basically, Xdebug does internally:

$cmd = sprintf("%s = %s", $name, $data);
eval($cmd);

where $name is the -n option and $data the -- option. As you can see that
without the "'s, the eval command is not valid. I will keep this report
open though as a reminder to properly implement property_set.
