why editor/code style/shell script not support customer `line_comment_at_first_column = false`

`line_comment_at_first_column` support most code formats

but not work with shell script

I add `.editorconfig` also not work, and waring `the property is not support`

I comment line and format with shfmt, it looks very bad!

- commnet

then format

how to suitable cooperation with shell script format comment `line_comment_at_first_column = false`

and shfmt running format good!
