Remove spaces from text

Strips every space, tab and line break so the text becomes one unbroken string. Useful for a key, a hash or a number that has picked up spaces from being wrapped.

The reason this specific operation comes up so often is copy-paste from displays that wrap long strings: an API key shown across three lines in a dashboard, a card number printed in groups, a hash in a terminal. Pasting it back with the spaces intact means it will not validate, and the spaces are frequently invisible in the field you are pasting into. Note that this removes spaces between words too — for prose you almost certainly want the collapse option instead, which keeps single spaces and only removes the extras.
