[Rpm-maint] [rpm-software-management/rpm] rpm's doFoo function tends to expand twice (#313)

[Jeff Johnson]

Ah, got it.

Lots depends on what you expect of %dirname as a "primitive".

If you consider %dirname as, say, strrrchr(str, '/') with appropriate checks on return value, then there isn;t a needs for an expansion per se.

But if you consider %dirname as a dirname(3) argument, then a fully expanded string argument is needed, just like any "primitive" system call.
