(New) Git, History: something is really wrong (for non top level), "boot/freeldr/freeldr/arch/i386/pcmem.c" case

Expected history: SVN and deprecated Git mirror
All SVN revs

NB: Last SVN rev is r76032.

–

Broken history: new Git mirror
New Git revs Then a list of useless merges and whatever else

NB: First new Git rev is:
rev c2c66aff7dacc62d125f2cd61d1167e9a2aa3fd6

Git conversion: Make reactos the root directory, move rosapps, rostests, wallpapers into modules, and delete rossubsys.

I assume this issue happened during the SVN-to-Git conversion, not the first new revision itself.
