vim-patch:9.1.0778: filetype: lf config files are not recognized

          script for lf files (Andis Spriņķis).

LF (LFRC) *lf.vim* *ft-lf-syntax* *g:lf_shell_syntax*
*b:lf_shell_syntax*
For the lf file manager configuration files (lfrc) the shell commands
syntax highlighting can be changed globally and per buffer by setting
a different 'include' command search pattern using these variables:
let g:lf_shell_syntax = "syntax/dosbatch.vim"
let b:lf_shell_syntax = "syntax/zsh.vim"
These variables are unset by default.
The default 'include' command search pattern is 'syntax/sh.vim'.
LEX *lex.vim* *ft-lex-syntax*
Lex uses brute-force synchronizing as the "^%%$" section delimiter
