Because I believe the definition I gave of it implied it was two chars
wide.  But maybe I'm making wrong assumptions:

That autoupdate does not work at all on Unicos.  My suspicion is that
our test for GNUness of sed failed to diagnose this is GNU sed.

Could you please run this:

echo 'xyz-xY' | sed 's/\bx.\b/XY/'

and sed --version?

If the first one answers xyz-XY and the latter shows this is not GNU
Sed, then you'll have to go into tests/, rerun ./debug-111.sh, and
then run

        ../autoupdate -A .. -v <configure.in >update.log 2>&1

and send me update.log together with update-x.log.

        sh -x ../autoupdate -A .. <configure.in >update-x.log 2>&1

Thanks!
