Call get_oid_hex_algop() directly with 'the_hash_algo' to make the reliance on the global hash algorithm explicit rather than hiding it behind get_oid_hex().

I tried to modify all relevant functions to support calling 'repo->hash_algo'.
However, this failed the test:

not ok 26 - patch-id without repository # # cat >diff <<-\EOF && # diff --git a/bar b/bar # index bdaf90f..31051f6 100644 # --- a/bar # +++ b/bar # @@ -2 +2,2 @@ # b # +c # EOF # nongit git patch-id <diff

repo=NULL happened here. 

I can't think of a particularly good way to solve this, so I didn't bother with it anymore. In other words, replacing the_repository with repo here isn't worth the effort IMO.

At least for now, this section is no longer "secretly" reading global variable.

Regards, Yuchen
