Currently immovable classes, hence classes using them will not offer move
facilities:

    std::streambuf,
    std::ios

Singleton classes are not provided with move facilities: there's never another
object:

    arg
    argconfig

Move aware classes:

    CGI
    CmdFinderBase
    CmdFinder
    ConfigFile
    Glob
    Hash
    Hostent
    MailHeaders
    Pattern
    Stat
    TableSupport
    TableLines
    User

No need for move-operations (no class type data members, no move-operations
                            defined in the base class, streams, or obsolete):
    Arg
    ArgConfig
    DateTime
    Errno
    FnWrap
    FnWrapXY    (obsolete)
    Fork
    GetHostEnt
    Hostname
    Indent
