join bug?

[german rigau]

Just in case this is really a bug...

I'm using version 5.2.1 of coreutils on a fedora core 4.

Consider joining these two files ordered with default options:

address@hidden BaseConcepts]$ more kk1.sort
ice_cream%1:13:00::
life_style%1:07:00::
part-time%3:00:00::
address@hidden BaseConcepts]$ more kk2.sort
icecream%1:13:00:: 07510835 1 0
ice_cream%1:13:00:: 07510835 1 1
life_style%1:07:00:: 04875322 1 2
part-time%3:00:00:: 01131371 1 21
address@hidden BaseConcepts]$ join kk1.sort kk2.sort
life_style%1:07:00:: 04875322 1 2
part-time%3:00:00:: 01131371 1 21
address@hidden BaseConcepts]$ join -v 1 kk1.sort kk2.sort
ice_cream%1:13:00::

Why ice_cream%1:13:00:: is not joined? Is this corrected in
version 5.93 of coreutils?

Thanks,

German
