   It ain't. `+' is a legal filename character in Unix but not in DOS. In DOS,
   `+' is a wildcard of some sort. DOS filenames can only contain 0-9 A-Z
   _^$~!#%&-[]()@`'

OK, OK, I get the point, I don't need any more education.  :-)  But as
long as we're here....

Since the restriction is at least partially a COMMAND.COM restriction,
not a DOS restriction, one should be considerate of other shells.
4DOS for one gets very upset about ^%@`', and I think that [] also
cause problems (although the parser may be context sensitive enough to
tell the difference between that usage and the use in variable
functions).  In fact, COMMAND.COM also should be unable to access a
file name with % in it, since that's the environment variable prefix.
