[frafra]

Fix #2738.

Tested. No regression found.

Is this patch eligible to be backported to OSGeo:releasebranch_7_8?

clang-format complained about my code style, but I was just using the previous convention. I fixed the style error.

Your changes only shortened the code, thus now fits in one line (80 col).
There is nowadays (only recently added and accompanying updated submitting guides are still missing [note to myself!]) only one formatting "convention" and that is clang-format.

Oh, right, got it, thank you :)

This looks like a reasonable change to me.
Considering GRASS GIS 7.8.8RC3 has been released, only breaking fixes should go to 7.8.8 at this time, this doesn't seem like such...

There is a failing test, but it is because of a timeout, not because of my code.

Looks good to me. This is what the GDAL API documentation actually recommends: https://gdal.org/doxygen/ogr__api_8h.html#a88facf4f8e8b32278101d52ae094255c
