[oncebo]

Change line spacing to 1 to match the real Nature citation style.

Improve numeric formatting in the bibliography to make it more compatible with Word processors, avoiding unwanted line breaks after the reference number.

Thank you for your PR.
Can you explain why you suggest this change?
In the guidelines I see "Contributions should be double-spaced and written in English (spellings as in the Oxford English Dictionary)."

[oncebo]

Thank you.
I checked the published Nature papers, and the line spacing used there is not double‑spaced, so I changed it to match the actual format.
The other extra blank in the numeric format is an unknown bug in some text editors, which causes an unintended line break in the bibliography information. Adding an extra blank can help to fix this issue.

[POBrien333]

I understand. Many publisher request a certain style though and then do the typesetting themselves. So, unless an editor at Nature has requested this I am not sure we'd accept this change.
