    st: Remove wrong indentation
    
    GObject-Introspection started warning for wrong annotations, and
    StGenericAccessible::set-current-value has a return value annotation
    even if it returns nothing. This generates the warning:
    
    src/st/st-generic-accessible.c:146: Warning: St:
    StGenericAccessible::set-current-value: invalid return annotation
    
    Which, coupled with fatal warnings, breaks the Shell build.
