Suggestion: Allow two consecutive blank lines

[jfschaff]

A common practice in code style is to have 3 possibilities regarding blank lines between statements and blocks: no blank line at all, 1 blank line, or 2 blank lines.

It is common to group statements that are closely related, or to separate function blocks by a single blank line for readability.

In the Python world, PEP8 recommends to "surround top-level function and class definitions with two blank lines" (see https://peps.python.org/pep-0008/#blank-lines).

In my opinion these 2 blank lines greatly improve code readability.

Yet Prettier only allows zero or 1 blank line, but not 2.

Is this point open to discussion? Can Prettier's opinion evolve on that matter?

I have implemented it naively but would need approval and maybe advice on how to do it "well".

PS: I know that:

1. Prettier is an "opinionated code formatter" ;
2. "Prettier has a few options because of history. But we won’t add more of them." (https://prettier.io/docs/en/option-philosophy)
