Include trailing {}s in raw latex commands.

Change is in rawLaTeXInline in LaTeX reader, but
it affects the markdown reader and other readers
that allow raw LaTeX.

Previously, trailing `{}` would be included for
unknown commands, but not for known commands.
However, they are sometimes used to avoid a trailing
space after the command.  The chances that a `{}`
after a LaTeX command is not part of the command
are very small.

Closes #5439.
