Although unfortunate (it would be nice to remove the global), this makes
sense. Disabling replace refs needs to be process-wide, and manually
propagating a repository setting to other repositories would be awkward
and prone to error.
All of my questions on this patch ("why were the 'disable_replace_refs()'
calls added later in the function than the original 'read_replace_refs =
0'?" and "why was '#include "environment.h"' added in 'repo-settings.c'?")
were asked [1] and answered [2] already. Beyond those two points, this patch
looks good!

Thanks for including the function documentation. It concisely explains the
purpose of 'disable_replace_refs()' and helps clarify how replace refs are
treated in Git.
