KSR-Yasuda created an issue (vim/vim#19619)

Steps to reproduce

Shell functions which names begin with do are not folded with foldmethod=syntax.

function foo() {        # - OK: fold lv.1
    return 0            # |
}                       # | until here

function dofoo() {      # - NG: fold lv.1 expected, but unfolded
    return 0            # |
}                       # | until here

shFunction{Two,Four} are supposed to be excluding functions named doFOOBAR.
https://github.com/vim/vim/blob/b8b7df29c418b93fa3d8607ae22f10701fa168d6/runtime/syntax/sh.vim#L653-L683

In bash, function doFOOBAR does work, at least.

If the region patterns just expect to avoid do ... done, the part \%(do\) shouldn't be something else?
(\%(\<do\>\)\@! or such, maybe.)

Expected behaviour

Functions named doFOOBAR() are folded.
