[PATCH 2/2] Some cosmetic changes to remote library

[Daniel Barkalow <barkalow@iabervon.org>]

Functions for managing ref lists were named based on their use in
match_refs (for push). For fetch, they will be used for other purposes, so 
rename them as a separate patch to make the future code readable.
