I was going to point you to the drill, http://cygwin.com/acronyms/#PTC,
but I read the description of REG_MULTI_SZ keys again.  It's definitely
defined as a list of null-terminated strings, with an empty string (aka,
one single \0) terminating the list.  Applications requesting a
REG_MULTI_SZ value will not expect an empty string in the middle since
that's against the definition.  If you try to add such a REG_MULTI_SZ
value using RedEdit, you'll get an error message "Data of type
REG_MULTI_SZ cannot contain empty strings. Registry Editor will remove
the empty string found."  What's the deal to change regtool to support
that?
