why not return bool ?

Done.

Done. Also fixed other instances in this file.

I wonder if, rather than adding these extra APIs, it would be sufficient to
create a CommandLine where the "program" was the empty string?

Yes, I propose to fix and cleanup CommandLine code in a new prerequisite
blocking Issue.

[msw, 2011/02/16 23:15:53]

I'll follow up on the extensive amount of needed CommandLine cleanup work with
Issue 73195; this should suffice in the mean time. Please let me know if you
disagree.

we don't use PCWSTR replace with const wchar_t*

Done.
