Formatting issue: Command in quoted subshell with HEREDOC should not be moved to newline

[openjck]

Thanks for a great tool.

If you disagree and think this is just a matter of personal preference, no problem. Feel free to close. I think it looks a bit odd, but perhaps it makes sense in other contexts.

I'm using shfmt 3.12.0.

I use docopts in my shell scripts. Using docopts requires running eval "$(docopts <<EOF. shfmt moves the word docopts and everything after it to a new line, which I think looks odd. Here's a file before and after formatting. I would rather "shfmt" leave Before unchanged.

This is a case where I would have used something like # shfmt-disable-next-line if it were available, to prevent shfmt from changing this line, but the shfmt docs recommend opening an issue instead when one feels like doing that, so that's why I've opened this issue.

Before

#!/usr/bin/env bash

eval "$(docopts --help=- -A ARGS : "$@" <<EOF
Run "ls". This is just an example for a bug report.

Usage:
	example-command
	example-command -h | --help

Options:
	-h, --help
		Show this documentation
EOF
)"

ls

After

#!/usr/bin/env bash

eval "$(
	docopts --help=- -A ARGS : "$@" <<EOF
Run "ls". This is just an example for a bug report.

Usage:
	example-command
	example-command -h | --help

Options:
	-h, --help
		Show this documentation
EOF
)"

ls
