Subject: [PATCH] ash: make 'sleep' a builtin

[shawnlandden at tutanota.com]

Thanks for merging this feature.

The builtin is exiting ash in two cases:

1.If no argument is given (also does not print usage of sleep, but ash---look at how printf handles his)
2.If xatou() interpretation of the number fails. This is a bit more involved to fix, which is why I didn't send my patch for #1.
