I made some changes to the original pull request to remove complexity which
I believe was not needed.

From the discussion on #1013:

Since the rule in VS is packages/*, the fact that it contains a slash means
that it is anchored to the top level. That is, is will only apply to
a directory called packages at the top level, and not to any at deeper
directories like App_Data. So these rules at the bottom of your changes
actually aren't necessary after all. I just confirmed this with a quick test.

Fix EOL issues in multiple gitignores

Some files don't contain a line separator ('\n') at the end. Add the
missing eol.

In POSIX, all lines of text should end with a newline character by
definition. See
http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap03.html

See https://gist.github.com/jacknagel/1020172 for a gist of the issue.

When working with multifile LaTeX-documents in AUCTeX in emacs, it creates the auto-folder to keep track of styles, macros etc. in the whole document. Unnecessary of versioning purposes.

Reftex adds these for internal processing, only auxillary files for composition and compilation of tex-documents.

xcuserstate files are generated from within Xcode and saved in your project bundle to remember your last opened file, the open state of any group folders, open tabs, and any other user setting your project might need to remember, this is something that shouldn't be tracked in version control
