Index files overlooked by texi2dvi

[Todd M. Lewis]

Dear sirs,

Sebastiano Vigna <address@hidden> and I work on a project whose
documentation  contains a defined index "co". However, when texi2dvi
filters the xref files, it searches for candidate index files with this
code:

    index_files=`echo "$orig_xref_files" \
                 | sed "s!.*\.aux!!g;
                        s!./$filename_noext\..o.!!g;
                        s/^[ ]*//;s/[ ]*$//"`

This could be good, but the ".o." in the 3rd line matches our index,
"co", followed by a space. The problem is that the last dot in

                        s!./$filename_noext\..o.!!g;
really be [^ ],
                        s!./$filename_noext\..o[^ ]!!g;

to guarantee that a real "log" file or similar is matched while not
skipping defined indices with two letter names the second of which is
"o".

It's a little thing, but so many things are...
Thanks for your time.
