Will this tell me why changing the version number of my terminal stops the mouse from working correctly in Vim? Oh "If you can still reproduce it now, it's most likeley a bug in Vim itself! Report it to the vim_dev mailing list." That didn't work out very well when I did it.
https://github.com/vim/vim/issues "If nothing else works, report bugs directly: Bram Moolenaar Bram@vim.org"
I might try that eventually.
