Why do you want it?

Speaking *only for myself*, I'd find unified diff a big deal easier to read.

Yes. Main target name appear in target path for a reason. Consider:

        exe test_lje.exe : test_lje.cpp   ;
        exe test_lje_d.exe : test_lje.cpp : <define>DEBUG_EVERYTHING ;

If main target name is not in target path, objects compiled with different 
settings of DEBUG_EVERYTHING will be placed in the same directory.
BTW, this behavour will somewhat change in the new build system, but still 
build system will take care of target path. Why would you want to change the 
logic?
