Subject: merge-recursive: Create function for merging with branchname:file markers
X-Git-Tag: v1.7.7-rc1~28^2~13
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=dac4741554e7672e69d1bc6b4f912cd16ad83b38;p=git.git

merge-recursive: Create function for merging with branchname:file markers

We want to be able to reuse the code to do a three-way file content merge
and have the conflict markers use both branchname and filename.  Split it
out into a separate function.
