removes whitespace before multiline comment on line-separated multi-argument function call

[matthargett]

oddly, it turns -- [[ isEdited ]] into --[[ isEdited ]] (removing the space before the --).

            local editedAST = visit(ast, {
                OperationDefinition = {
                    enter = function(self, ...)
                        local node = ...
                        checkVisitorFnArgs(expect, ast, { ... })
                        selectionSet = node.selectionSet
                        return Object.assign({}, node, {
                            selectionSet = {
                                kind = "SelectionSet",
                                selections = {},
                            },
                            didEnter = true,
                        })
                    end,
                    leave = function(self, ...)
                        local node = ...
                        checkVisitorFnArgs(
                            expect,
                            ast,
                            { ... },
                            true --[[ isEdited ]]
                        )
                        return Object.assign({}, node, {
                            selectionSet = selectionSet,
                            didLeave = true,
                        })
                    end,
                },
            })

Doesn't seem to just be for function argument calls
The following:

local test --[[foo]] = true

gets formatted as

local test--[[foo]] = true
