Subject: vim-patch:partial:9.0.1166: code is indented more than necessary
 (#21716)

Problem:    Code is indented more than necessary.
Solution:   Use an early return where it makes sense. (Yegappan Lakshmanan,
            closes vim/vim#11792)

https://github.com/vim/vim/commit/1cfb14aa972ccf3235ac67f07b7db1175b7c5384

Partial port as some highlight.c changes depend on previous patches.
Cherry-pick fname_match() change from patch 8.2.4959.
Omit internal_func_check_arg_types(): only used for Vim9 script.

N/A patches for version.c:

vim-patch:9.0.1167: EditorConfig files do not have their own filetype

Problem:    EditorConfig files do not have their own filetype.
Solution:   Add the "editorconfig" filetype. (Gregory Anders, closes vim/vim#11779)
