Use this when Amazon gives you an "Encoded authorization failure message" and you need to turn it into something readable. If you only get a request id... you're out of luck.

##git mergetool

In the middle file (future merged file), you can navigate between conflicts with ]c and [c.

Choose which version you want to keep with :diffget //2 or :diffget //3 (the //2 and //3 are unique identifiers for the target/master copy and the merge/branch copy file names).

:diffupdate (to remove leftover spacing issues)
:only (once you’re done reviewing all conflicts, this shows only the middle/merged file)
