You quoted only half the diff!

What happens is that the line
[1.0000000000000000000000000000000000000 1.0806046117362794348018732148859532075]

becomes
[ 1.0000000000000000000000000000000000000   1.0806046117362794348018732148859532075]

because it is targeted to 85 characters output instead of 80.
but then the benchmark cut the line to 80 characters, so finally
the two lines in the original benchmark

[1 -1.2833494518006402717978106547571267252 0.283349451800640271797810654757
12672521]

becomes
[ 1  -1.2833494518006402717978106547571267252 0.2833494518006402717978106547
5712672521]

In any case, I have fixed src/test/dotest to unset COLUMNS to avoid this issue.

Cheers,
Bill.
