I don't see the problem: the value 71 is the last value that
fill-column had before it was changed with customize. That's why
erasing customizations brings back this value.
Do you use Custom at all? The problem is so obvious that I do not
know what there is to explain. "Erase Customization" is supposed to
restore the standard value (or themed value if there are themes) and
_not_ the last _rogue_ value assigned to the variable, which may have
been assigned ages ago, and changed twenty times through Custom since.
That value is meaningless, which is why that `changed' theme is
completely meaningless and should be eliminated.
What I described above constitutes an incompatible change, which
eliminates completely essential and well documented functionality
(reverting to the default) and replaces it with nonsensical behavior.
It is a serious bug.
Sincerely,
Luc.
