Incorrect formatting of `using EllipsisNotation: :..`

[lassepe]

The package EllipsisNotation.jl exports the symbol .. which can be imported as using EllipsisNotation: :... However, JuliaFormatter will format that as using EllipsisNotation: : .. (not the extra space between : and ..) which is not valid syntax in Julia.

The formatter also gets this incorrect if you use parentheses like this, which should be valid:

using EllipsisNotation: (..)
