Here documents not working due to indentation

··# src/hello_command.sh
··cat << EOF
··hello

Can't be helped. Heredocs are a messy language construct that rely on improper indentation.

See #73 and #163

I have added an example of the only way to use heredoc in bashly.

Bashly 0.7.10 was released, with improved support for cases where heredoc is needed.

By settings the BASHLY_TAB_INDENT=1 environment variable (or via the new settings.yml), the generated script will have all its leading spaces indented as tabs instead, which allows use of this heredoc format:

cat <<-EOF
multiline
heredoc text
EOF

See the heredoc example.

I have made heredoc work naturally, without the need to do anything (#496). bashly will no longer apply additional indentation to the strings inside a heredoc block.

This is available in the edge version, if anyone wishes to test it.
