<-------------------

I checked out a src tree, and when I tried to compile a kernel,
I encountered corrupted file content.

Specifically, the first 1132 bytes of

  sys/dev/pci/drm/amd/include/asic_reg/gc/gc_9_0_sh_mask.h
  sys/dev/pci/drm/amd/include/asic_reg/gc/gc_9_2_1_sh_mask.h

are overwritten with the start of

  gnu/usr.bin/perl/lib/unicore/TestProp.pl

Well, the first line reads

# !!!!!!!   DO NOT EDIT7THIS FILE   !!!!!!!

with an erroneous '7', so even the corruption is corrupted.

I used "got tree -i" to get the blob IDs for the two files, and
"got cat <hash>" shows what looks like correct content.

However, "got blame" fails:  got: value out of range

I checked out another copy of the tree from the repository, and it
shows the same corruption.

got 0.65-current, as of commit 0f71f6196dbf9f3afd34524586b8bfdb2d1eaccd.
Oh, hmm, that would be got 0.66-current, but I forgot a "make clean",
and there's no dependency on got-version.mk.
