In handle_rename_rename_1to2(), we have duplicated error handling
around colliding paths. Specifically, when we want to write out
the file and there is a directory or untracked file in the way,
we need to create a temporary file to hold the contents. This has
some special output to alert the user, and this output is
duplicated for each side of the conflict.
Simplify the call by generating this new path in a helper
function.

Elijah,
Here is a patch that combines the logic to avoid code clones, and also
more easily covers code blocks. Of course, your additional test helps
the branch coverage.
Thanks,
-Stolee
