This should have been fixed in pkg_install two weeks ago, and was what
prompted the PKGTOOLS_REQD bump in pkgsrc. Are your pkg_install tools
up-to-date? If so, this is still a bug and you should file a PR.

The +INSTALL script unpacks several stand-alone helper scripts (+DIRS,
+FILES, +RCD_SCRIPTS, etc.) when it is run for the first time. These
lines are simply in each of those subscripts. While I could have used a
more sophisticated implementation that generated the helper scripts on
the fly, I thought that would make creating and maintaining the helper
scripts much harder than it should be. I chose instead to embed the
complete scripts directly into the +INSTALL script. This simple
mechanism is both easy to use and to debug.
