Strings of the form %FOO% in cmd.exe commands are expanded iff FOO is
an existing environment variable; otherwise, the string is left alone.
All other uses of % are likewise left alone.  This expansion is done
*before* quotation marks are interpreted, so there is no way to escape
it; you simply have to hope that you don't get hosed by it.

We are lost, lost.  No name, no business, no Precious, nothing.  Only empty.
Only hungry: yes, we are hungry.  A few little fishes, nassty bony little
fishes, for a poor creature, and they say death.  So wise they are; so just,
so very just.  --Gollum        address@hidden  http://ccil.org/~cowan
