Fails to replace macros with names in the tags list

[zakkak]

Consider the following two spec files

min.spec

%global version 1.2.3
Version: %{version}

and min_ok.spec

%global myversion 1.2.3
Version: %{myversion}

replace_macros does not work for the former, but works fine for the latter.

$ python3
