Feature request: maintain absent whitespace around binary operations

[kbarros]

Is it possible to add an option that would maintain absence of whitespace around binary operations?

Examples where this might come up in a code base:

• Keep [1/2, 1/3, 0] instead of [1 / 2, 1 / 3, 0].
• Keep x + y*z instead of x + y * z.
• Keep f(R; N=2k+1) instead of f(R; N=2k + 1).

Misleading cases would also be allowed, e.g., keep x+y * z instead of x + y * z.

There was some previous related discussion but I'm wondering if the approach described in this Issue is easier to implement?

This is what I always wanted in a code formatter. Currently, the extra spaces make the code more difficult to read. Perhaps, a operators black-list could be implemented.
