Because -fdump-rtl-expand-detailed includes *two* copies of the RTL: one 
lacks the prologue and epilogue but is interleaved with trees, the other 
is the standard -fdump-rtl-expand dump.

It is not merely an option name alias.  It came together with a redesign 
of the way RTL dumps work, to integrate their management with tree dumps 
and to allow (in the future) to have various levels of detail in the RTL 
dumps as well.

I never had a problem with the rename because I use fname*.00.* (or the 
analogous completion key sequence) to invoke an editor on the RTL dump 
(or in general any other dump).
