Fix coloneq etc (#1372)

Browse Source 
Fix issue #1333.

`\coloneq` and several similar functions are written as macros. When expanded, these result in atoms like ":" and "=" placed adjacent to each other at the top level. So they exposed to a split by an automatic line break.

This PR wraps each of these macros in an `\mathrel{ }`. This prevents the line break.
