I was not asking whether you removed all bugs from FriCAS, but rather
whether you intended to fix the "%iint in output" issue with this commit
and believe that you succeeded or whether you are *sure* that you left
some cases.

It is about conveying some information with the commit message. "Better"
tells almost nothing.

Anyway, I am happy that you fixed at least this one issue. Thanks.
