install-info is smart enough to add at least '.gz' when needed. Hence
the %_extension macro is not needed.

I used

| %__install_info		/sbin/install-info --info-dir=%_infodir
| %__install_info_post          g() { %__install_info "$@" || :; }; g
| %__install_info_preun         g() { %__install_info --delete "$@" || :; }; test "$1" != 0 || g

some time ago. I do not see much sense in the test-for-existence check;
when a packager uses

| %__install_info_post %_infodir/zsh.info

he knows that 'zsh.info' exists there (else, package would be broken).


I am not sure about automatic detection of pre/postun requires; perhaps
a similar approach like for fedora-usermgmt can be chosen and

| %FE_INSTALL_INFO_REQ	\
| Requires(pre):	%__install_info	\
| Requires(postun):	%__install_info

defined which is applied like

| BuildRequires: package-with-these-macros
| %{?FE_INSTALL_INFO_REQ}
