[Bug 608071] VUL-0: ghostscript: executes random code on startup (does not verify ownership of sensitive files used)

A proposal how to patch the documentation in Use.htm
for ghostscript-8.70 if SEARCH_HERE_FIRST=0 is used.

As far as I see it is sufficient to fix the documentation
in Use.htm because nowhere else is '-P-' mentioned
(in particular not in "man gs") and furthermore "gs -h"
points to Use.htm (below the "Search path" output).

By the way:

According to
the Ghostscript authors already agree that "trying the
current directory first is a very bad idea" because it
"opens serious security loopholes" but they didn't fix
the security bug only because some users complained :-(

I also agree that a parameter that makes gs safer does not matter
as long as it is not the default (see comment #12).

I think that at least all Linux distributions should fix
Ghostscript accordingly regardless if some users might
then complain that they must use the -P (or -I) switch
if they need the current directory.
