CVS_RSH env-var feature patch

[Daniel Hiltgen]

Existing behavior:  The entire environment variable is treated as
argv[0] for the fork, so you can not specify command arguments within
the variable.

Fix:  Use strtok to tokenize the env-var so that multiple arguments
show up as argv[0], argv[1], etc.  This also works for the scenario
where there is only a command and no arguments.

This is very useful for people who want to use ssh as the plumbing,
since ssh often requires multiple arguments to get the job done.
