Subject: fetch: get the remote branches to merge from the branch properties
X-Git-Tag: v1.4.3-rc1~44^2~1
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=5372806a849cf117596b1f7c8c7d512c519f8092;p=git.git

fetch: get the remote branches to merge from the branch properties

If in branch "foo" and this in config:

[branch "foo"]
      merge=bar

"git fetch": fetch from the default repository and program the "bar"
             branch to be merged with pull.
