   31   /* NOTE:Some argument types doesn't require a specifier,

   33    * difference between this and "Options=setSomething=true".)
   34    * In these cases, str will be null. This is perfectly valid.

Looks like a bug rather than a feature.

"Options=setSomething=true" is not a syntax originally supported
by the DCmdParser.

"Options,setSomething=true" is correct with the comma separator.
or
"Options="setSomething=true" is also correct.

But "Options=setSomething=true" should have been rejected.
Unfortunately, this error syntax doesn't seem detected.
