merge-recursive: clean up get_renamed_dir_portion()
Dscho noted a few things making this function hard to follow.
Restructure it a bit and add comments to make it easier to follow. The
restructurings include:
* There was a special case if-check at the end of the function
checking whether someone just renamed a file within its original
directory, meaning that there could be no directory rename involved.
That check was slightly convoluted; it could be done in a more
straightforward fashion earlier in the function, and can be done
more cheaply too (no call to strncmp).
* The conditions for advancing end_of_old and end_of_new before
calling strchr were both confusing and unnecessary. If either
points at a '/', then they need to be advanced in order to find the
next '/'. If either doesn't point at a '/', then advancing them one
char before calling strchr() doesn't hurt. So, just rip out the
if conditions and advance both before calling strchr().

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and Documentation/git-<commandname>.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with man gittutorial or git help tutorial, and the documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt (man gitcvs-migration or git help cvs-migration if git is installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just “subscribe git” in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://public-inbox.org/git/, http://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
The maintainer frequently sends the “What's cooking” reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name “git” was given by Linus Torvalds when he wrote the very first version. He described the tool as “the stupid content tracker” and the name as (depending on your mood):
