Allow longer commandlines in MOUNT and IMGMOUNT.
Fix crash reported by MiniMax (mount -u 0).
Fix bug reported by Tearex ("config -get" broken).
Add some protection that makes it harder to mount a directory from
within an executable.
Add some protection to make mounting from command /c much harder.
Add a securemode commandline switch to config and dosbox that should make it
impossible to mount a location when this isn't wanted by the user. (Addresses concerns of CVE-2007-6328)
Update documentation to reflect this.
