2011-07-12; install-sh is not robust to blanks in file names

Hello,

I had to install AUCTeX on a new MSWindows machine. The distribution was
MikTeX which by default contains a space in its texmf path. I followed
the instruction in INSTALL.windows, but the make install partially
failed because of this space. I attached a patch in the file mypatch.tgz.

Your bug report will be posted to the AUCTeX bug reporting list.
