With or without the nits fixed

as the nits are not degrading functionality.

Nit: According to our Codingguidelines we want to indent it further, so it
aligns with
the arguments from the first line.
+static int expire_reflog_ent(unsigned char *osha1, unsigned char *nsha1,
+ const char *email, unsigned long timestamp, int
tz,
+ const char *message, void *cb_data)

Why do we need the return value for expire_reflog_ent?
The "return 0:" at the very end of the function is the only return I see here.

Sometimes we align the assigned numbers and sometimes we don't in git, so an
alternative would be
enum expire_reflog_flags {
EXPIRE_REFLOGS_DRY_RUN = 1 << 0,
EXPIRE_REFLOGS_UPDATE_REF = 1 << 1,
EXPIRE_REFLOGS_VERBOSE = 1 << 2,
EXPIRE_REFLOGS_REWRITE = 1 << 3
}
Do we have a preference in the coding style on this one?

Also I know how we got here, I wonder if we should inverse the logic here
(in a later patch). "select" sounds to me as if the line is selected to keep it.
However the opposite is true. To actually select (keep) the line we need to
return
0. Would it make sense to rename this to reflog_expiry_should_prune_fn ?
