Merge branch 'mh/fetch-pack-constness' 

Tighten constness of some local variables in a callchain.

By Michael Haggerty
* mh/fetch-pack-constness:
  cmd_fetch_pack(): respect constness of argv parameter
  cmd_fetch_pack(): combine the loop termination conditions
  cmd_fetch_pack(): handle non-option arguments outside of the loop
  cmd_fetch_pack(): declare dest to be const
