patch 9.0.1946: filename expansion using ** in bash may fail Commit: https://github.com/vim/vim/commit/9eb1ce531527a7177d16373b0f8689bbcd3d5f73 Author: Christian Brabandt <cb@256bit.org> Date: Wed Sep 27 19:08:25 2023 +0200 patch 9.0.1946: filename expansion using ** in bash may fail Problem: filename expansion using ** in bash may fail Solution: Try to enable the globstar setting Starting with bash 4.0 it supports extended globbing using the globstar shell option. This makes matching recursively below a certain directory using the ** pattern work as expected nowadays. However, we need to explicitly enable this using the 'shopt -s globstar' bash command. So let's check the bash environment variable $BASH_VERSINFO (which is supported since bash 3.0 and conditionally enable the globstar option, if the major version is at least 4. For older bashs, this at least shouldn't cause errors (unless one is using really ancient bash 2.X or something). closes: #13002 closes: #13144 Signed-off-by: Christian Brabandt <cb@256bit.org>
