Enable calling commands with : in argv[1] (#9963)

The solution seems hackish, but it works: for
NMake only, prepend a no-op command before each
real command that begins with ".

This is really a work-around for an NMake problem.
When a command begins with ", nmake truncates the
first argument to the command after the first :
in that arg. It has a parsing problem.

Workaround..., hackish..., but it should solve
the issue for #9963 and its related friends.

Also, modify the CustomCommand test to replicate
the problem reported in issue #9963. Before the
NMake specific code change, the test failed.
Now, it passes. Ahhhhhh.
