Fix editconf -d not setting the unit cell correctly with -noc
Previously, editconf
did not compute the box largest dimensions, which is necessary for -d
to work, when -noc
was concurrently applied.
This fixes that, adds unit test for this particular behavior, as well as -c
and -c -d
Spiritual followup to 24-year-old 535e06a9 fixed a stupid bug with not setting the size
Fixes #4875 (closed)
