I think the commit message is fine as-is, but perhaps you intended to
include this paragraph from v4 [1]?
A logical follow-up to this would be to change the various "*_get_*()"
functions to ferry the git_configset_get_value() return value to their
own callers, e.g. git_configset_get_int() returns "1" rather than
ferrying up the "-1" that "git_configset_get_value()" might return,
but that's not being done in this series
Which is nice, but the commit message reads fine without it too.
