patch 9.0.2065: EXPAND flag set for filetype option Commit: https://github.com/vim/vim/commit/3932072ab435eb171ab55b2a2c0185358cd0d7bf Author: Doug Kearns <dougkearns@gmail.com> Date: Wed Oct 25 20:54:00 2023 +0200 patch 9.0.2065: EXPAND flag set for filetype option Problem: EXPAND flag set for filetype option Solution: Remove P_EXPAND flag from the 'filetype' option Remove P_EXPAND flag from the 'filetype' option Problem: P_EXPAND flag is erroneously set for 'filetype' option Solution: Remove the P_EXPAND flag This flag is used by string options that accept file path values. See :help set_env. This appears to have been included in d5e8c92 and resulted from an incorrect implementation of 'filetype' completion. See #12900 for a small discussion. related: #12900 closes: #13416 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Doug Kearns <dougkearns@gmail.com>
