indent tab_char not working properly, after any characters.

[TanawatJukmongkol]

Problem

As the title suggests, the tab_char settings is not working properly.

My config:

set     smartindent
set     noexpandtab
set     tabstop=4
set     shiftwidth=4
set     backspace=indent,eol,start
syntax  on
set     nu

require("ibl").setup {
    indent = {
        char = "→",
        tab_char = "→",
    },
    whitespace = {
        remove_blankline_trail = false,
    },
}

Steps to reproduce

-

Expected behavior

the ">" should have been swapped out with "→"

after any characters

indent-blankline only does indentation. Tabs after other characters are not indentation, so they won't get changed.
tab_char is for when you want to change the way tabs for indentation look, but leave the rest as they are.
If you want to change all tab characters, use the built-in Neovim feature :help 'listchars' instead.
