+         Use spaces (not ';') to separate args: _MSBuildArgs is passed as a
+         single quoted argument in the Helix PreCommands/Command, and Helix
+         treats ';' as a command separator when generating the run script
+         (that's why the env-var 'set ...;set ...' blocks work). A ';' here
+         would split the quoted argument across separate command lines. -->
