[PATCH 8/8] Re-implement 'git remote update' using 'git fetch'

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In order not to duplicate functionality, re-implement 'git remote
update' in terms of 'git fetch'.

Signed-off-by: Björn Gustavsson <bgustavsson@xxxxxxxxx>
---
The --prune option will be passed on, as 'git fetch' now
supports it.
