Bug#180127: install-info doesn't support new direntry format

[Michael Stone]

Package: dpkg

coreutils is using a new direntry format as follows:

@dircategory Basics
@direntry
* Coreutils: (coreutils).                         Core GNU utilities.
* Common options: (coreutils)Common options.      Common options.
* File permissions: (coreutils)File permissions.  Access modes.
* Date input formats: (coreutils)Date input formats.
@end direntry

@dircategory Individual utilities
@direntry
* basename: (coreutils)basename invocation.     Strip directory and suffix.
* cat: (coreutils)cat invocation.               Concatenate and write files.
...

The debian install-info doesn't parse this.
