Description

Proposal: add a skip whitespace format specifier to formattedRead.

The purpose of this is to enable stuff like: https://issues.dlang.org/show_bug.cgi?id=4656

Of note is that white space is a Unicode category, it covers a lot more characters than just space or tab.

This came up as a comparison to Nim, which does this automatically. However not skipping white space is intentional on D's side. So to have a format specifier for it would give us both capabilities when needed.
