10. If a file exists with the same name as the Session file, but ending
in "x.vim" (for eXtra), executes that as well. You can use *x.vim
files to specify additional settings and actions associated with a
given Session, such as creating menu items in the GUI version.
we already have Session.vim ignored. the Sessionx.vim file, like
Session.vim, is a user file. a user would generally want that file kept
private or for themselves, and the public or a team fetching from or
sharing the repository generally have no interest in a file relevant
only to a particular user. so it's a good idea to get git to help us
avoid mistakenly sharing the file.
When IntelliJ project is created as a file-based (i.e. without `.idea` folder, but with `.iws`, `.iml` and `.ipr` files), and this is a Gradle or Maven project with auto-import, should ignore them as well for the same reason we ignore `.idea` folder content in that case.
Netbeans Linux and Windows Makefile-*.mk and Package-*.bash files in nbproject directories are automatically generated during compile. These files are continually updated, which can cause a long list of unnecessary files to add, commit, and push (or that are Untracked). This has been experienced for Linux and Windows C++ projects.

If checked the option "Always create backup copy" under Settings -> Save within Microsoft Word 2016 on macOS, when editing a docx file, a folder named as same as docx file name(without ext) will be created and placed a docx backup file named "Backup of DOCX_ORIGINAL_FILENAME.docx".
Add extra commented section to use when using Gradle or Maven auto-import.
These are mentioned in the original reference for optional excludes (https://intellij-support.jetbrains.com/hc/en-us/articles/206544839).
If this would be better as a separate, non-commented ignore file, let me know and I will resubmit.
.idea/misc.xml used to contain usage statistics. This was broken out to usage.statistics.xml in the latest EAP (2018.2 EAP). It should be excluded from git.
