[Pkg-octave-devel] Bug#368843: Broken info-emacs-info

You will find attached below a bug report filed against the Debian package
octave2.9 regarding the info-emacs-info script.  The followups to this bug
reported can be seen at:

    http://bugs.debian.org/368843

The info-emacs script seems to be still broken in CVS.  As the reporter
writes, the order of the options in the invocation of INFO_PROGRAM
changed (--directory comes before --file now) and the old info-emacs-info
script gets confused.

Here is a patch that fixes the problem.  Notice that I replaced the call to
the deprecated gnudoit by a call to gnuclient.

Package: octave2.9
Version: 2.9.5-7
Severity: normal

Using `info-emacs-info' (within Emacs) makes the command `doc' fail with 
the error message:

 error in process filter: byte-code: Info file /usr/share/info does not exist
 error in process filter: Info file /usr/share/info does not exist


I think the problem lies in the order of the arguments passed to the 
info program, which is different from what `info-emacs-info' expects.

Issuing

 doc "whos"

in an Octave terminal outside Emacs launches the program (as shown by 
"ps x"):

 info --directory /usr/share/info --file /usr/share/info/octave2.9.info --index-search whos

while the first line of `info-emacs-info' is

 cmd="(Info-find-node \"$2\" \"Top\")"


A simple experiment from a bash confirmed this: when `--file' is the 
first option passed to the info program, `info-emacs-info' works.

Bernardo
