Texinfo4.8 can not handle blank lines in @direntry

[Luc Teirlinck]

The file org.texi used to contain the following @direntry:

@direntry
* Org Mode: (org).      outline-based notes management and organizer

@end direntry

I know that this was a non-standard entry and, in fact, I already
deleted the blank line from the Emacs CVS version of org.texi.
However, I nevertheless believe that Texinfo should be able to handle
blank lines in @direntry's better than it apparently does.

Running install-info on the above in Texinfo4.8 apparently deletes the
blank line below the "Org Mode" entry and moves it above the entry.
The next time I run make-install on the Emacs CVS, the blank line
above the "Org Mode" entry moves up one extra entry and the blank line
in the @direntry makes a new blank line above the "Org Mode" entry.
As I keep running make-install on the Emacs CVS, the number of blank
lines in my dir file goes to infinity: eventually I get an ever
growing run of blank lines between the first and second entries.

I had to manually remove all blank lines in my dir file (in addition
to removing the blank line in the @direntry) to get rid of the problem.

Sincerely,

Luc.
