documentation bug in varsym man page

[Dave Leimbach <leimySPAM2k@xxxxxxx>]

 -p            This option causes variables to be set on a per-process
                   basis and restricts retrievals to process-specific vari-
                   ables.  Note that since varsym is run as its own process,
                   using this option to set a variable will not effect your
                   shell's namespace.

should be "affect your shell's namespace."
