              broke the ability to redefine build.cmd as a
              series of commands

Comment:

 I'd rather say it's build.nice feature that broke the possibility to
 redefine build.cmd as a series of commands :)

 build.cmd "cmd1 && cmd2" -> cmd1 will be niced, not cmd2

 build.cmd "shell stuff cmd" -> shell stuff will break (where shell stuff
 can be a built-in such as unset as here, or VAR=X)
