Shell.mkdir on OSX

[Sean McLaughlin]

Hi,

Shell.mkdir ~perm:0o777 "foo"

runs

/bin/mkdir --mode 777 foo

--mode is not an option on OSX. -m works on both. Should we

1) change the flag (which could lead to many such changes)
2) do conditional directives as in other os-dependent modules
3) Assume Shell only works on Linux and write our own OSX Shell module?

Another option is to use gmkdir on OSX, from the gnu-coreutils
package, but that's another conditional.

-m seems like the better solution. I'll get a quick patch to that
effect into our current tree.
