Hi Tom, Matthias,
The code for handing file overwrite incorrectly assumed that the file on disk is always contiguous. This resulted in corrupting disk structure every time when write to existing fragmented file happened. Fix this by adding proper check for cluster discontinuity and adjust chunk size on each partial write.

This patch partially fixes the issue revealed by the following test script:
Tom could you pic this patch and the following one (2/6): https://patchwork.ozlabs.org/patch/1203101/
to -master as a fix?
This seems like a _real_ fix for FAT.
Right, I think the first patches should go in for v2020.01. I can send them together with some fixes for RPi I'm working on.
Tom what do you think?
I'd _really_ like to see the test that's in the commit message turned in to a test we can run from CI as Travis will be doing those Soon(TM) and GitLab/Azure do. Then I'll pick them up (I'm testing some other fat fixes right now). Thanks!
