+INSTALL and +DEINSTALL scripts:
PKGINSTALL_VERBOSE
A list of scriptlets that will be verbose and output a message
noting the actions taken.
* "all" is a special value that implies all of the other items
* "fonts" for +FONTS
* "info-files" for +INFO_FILES
Default value: "all" for PKG_DEVELOPERs, empty otherwise.
* Be "one-liner brief" when doing the default actions. For example,
the info files output now looks like:
gmake-3.81: registering info file /usr/pkg/info/make.info
We retain the current verbosity for the CHECK-* actions.
