Running v fmt -w gemv_test.v formats a file in an oscillating manner, when run several times, without stabilisation.

What did you do?
./v fmt -w ~/.vmodules/vsl/float/float64/gemv_test.v

... which was from https://github.com/vlang/vsl/ .

See the attached file gemv_test.v.txt

What did you expect to see?

After v fmt -w gemv_test.v there should be a stable result.
Running v fmt -w gemv_test.v a second and third time, should not change the file anymore.
The stable version should be preferably the shorter one, that does not wrap for just a few characters.

What did you see instead?
Running v fmt -w gemv_test.v makes the formatting of the file oscillate between 2 states every time it is run.
