Replaces spaces with tabs

[sputnik-adam]

When copying code from an editor, or output from a shell, into Google Docs and running Code Blocks against it, groups of spaces are replaced with tabs. This causes the formatted code, which had the correct space counts for things like tabulated terminal output and code indentations, to become messy and misaligned.

This should not be the default behaviour and at the very least should be configurable with a checkbox on the sidebar.
