[Rpm-maint] [rpm-software-management/rpm] How to expand user possibly non-existent user constructed variable name? (Discussion #3411)

[Vít Ondruch]

Actually, it seems that I have found a cure:

~~~
$ rpm -D "name foo" -D "string_io_prerelease .dev" --eval '%{expand:%{%{quote:?}%{gsub %{name} - _}_prerelease}}'

$ rpm -D "name string-io" -D "string_io_prerelease .dev" --eval '%{expand:%{%{quote:?}%{gsub %{name} - _}_prerelease}}'
.dev
~~~

But why the `quote` macro makes a difference?
