`--indent 0` omits more than indentations

[zstadler]

Describe the bug

jq --indent 0 behaves like jq --compact-output rather than only omit the indentations.

To Reproduce

jq --indent 0 -n "[1,2]" produces

[1,2]

Expected behavior

I would expect jq --indent 0 to keep lines separated and only avoid adding the indentations.

For example, jq --indent 0 -n "[1,2]" should produce

[
1,
2
]

In other words, jq --indent 0 ... should be equivalent to jq ... | sed 's/^\s*//' on Linux.

Environment:

• OS and Version: Windows, Linux - WSL
• jq version 1.6
