Beats me :/.  Even after reverting commits a0f60293d9 and 88ca2280ba,
'make check' still fails.  But both 'git bisect', and checking out its
parent 6ad9b8d677, point to a0f60293d9 as being the culprit.

Not the kind of nom de plume you see every day.

Thanks, pushed with the log message adapted accordingly.
