patch 8.2.0413: buffer menu does not handle special buffers properly Commit: https://github.com/vim/vim/commit/5e94a29ebbde10dd973d58f1adba9a2fc83877d1 Author: Bram Moolenaar <Bram@vim.org> Date: Thu Mar 19 18:46:57 2020 +0100 patch 8.2.0413: buffer menu does not handle special buffers properly Problem: Buffer menu does not handle special buffers properly. Solution: Keep a dictionary with buffer names to reliably keep track of entries. Also trigger BufFilePre and BufFilePost for command-line and terminal buffers when the name changes.
