Issue reporting guidelines

• Search the existing open and closed issues. Maybe the bug was already reported?
• Mention your terminal (if you use the terminal version), vim version, font used. Also terminal related things such as tmux/screen, $TERM, or similar things should be mentioned
• Describe your issue properly. If you spend 30 seconds throwing out a sloppy report, do expect that others will spend exactly the same amount on trying to resolve it.
• Include a Minimal, Complete, and Verifiable example using GitHub Markdown's codeblock delimiters.
• Be prepared to test fixes!
• Be polite. You are asking highly competent software developers for help, for free, so you might want to avoid treating them as if they were a commodity or at your free disposal.
• For further inspiration, read reports that were resolved successfully, http://www.chiark.greenend.org.uk/~sgtatham/bugs.html, http://stackoverflow.com/questions/how-to-ask and http://whathaveyoutried.com/.
