It is a side effect of the change that removed the double quote " from
the list of special characters for the Windows shells. (The reason
for that was to avoid hitting the command-line length limitations of
the Windows shells, which are 4KB or 8KB, depending on the Windows
version, while the limit imposed by the OS is 32KB.)
So now commands that use quotes go through the fast path, instead of
being submitted to cmd.exe via a batch file, which exposed these
commands to this (very old) bug.
I fixed that in the repository; the patch is below if you want to try
Please also tell me if your original problem was fixed by the patches
I sent earlier. Thanks.
