(http://www.open-mpi.org/community/lists/users/2011/01/15427.php), the
--tv (and friends) switches to mpirun would effectively munge the
orterun command line together and then split it apart again before
exec'ing the underlying debugger. We would therefore lose multi-token
argv[x] value and split them into multiple tokens. For example:
mpirun --tv -np 2 a.out "foo bar"
would get launched with "foo" and "bar" as separate arguments; not one
argument. This was due to the underlying code joining the argv into a
single string and then re-splitting it. This commit removed the argv
join; it now does the parsing and re-jigering of the argv by only
looking at each individual argv item; multi-word tokens like "foo bar"
will never be split into separate tokens.
This commit was SVN r24322.
