patch 9.1.0110: filetype: add 'Config.in' filetype detection Commit: https://github.com/vim/vim/commit/5f20f050efed3431beaf85739f0113e9ef0abd8e Author: Brandon Maier <brandon.maier@collins.com> Date: Wed Feb 14 22:30:06 2024 +0100 patch 9.1.0110: filetype: add 'Config.in' filetype detection The 'Config.in' file type is for Buildroot configuration files. Buildroot Config.in files use the same Kconfig backend as the Linux kernel's Kconfig files. Buildroot also has other filename variants that follow "Config.in.*", they are used to distinguish multiple Config.in files in the same directory. See https://buildroot.org/downloads/manual/manual.html#_literal_config_in_literal_file closes: #14038 Signed-off-by: Brandon Maier <brandon.maier@collins.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
