bug#42513: Python indentation bug when using multi-line on an if-condition

[swedebugia]

Hi

The following code indents correctly:
def fun(arg):
        if(                                                     
args.suppliername == "x"):
                #do something
        else:
                #do something

The following code does not indent correctly:
def fun(arg):
        if(                                                   
args.suppliername == "Messingschlager" or          
args.suppliercodename == "MS"
        ): #<- culprit
                #do something
else: #<- this else is not possible to indent 1 tab
                #do something
