Highlight error assertion operator bold red

! is highlighted bold red when it appears immediately after a closing
parentheses that wasn't part of a comment, and is not immediately
followed by an equals sign.

Note that this only works when ! comes after a function call, as it
almost always does. Handling all edge cases where ! is used after a
non-call expression is, if not impossible, extremely impractical without
the use of semantic analysis.
