Comment (by warner):

 Updated table for `cp [-r] X local/`, where `local` already exists:

 =||= command =||= FILECAP =||= DIRCAP/file =||=  =||= PARENTCAP/dir =||=
 DIRCAP     =||= DIRCAP_ALIAS: =||=
 || cp       || -       || local/file  ||   || ERROR-4b       || -
 || -             ||
 || cp -r    || -       || local/file  ||   || local/dir/file || -
 || -             ||
 || cp -R    || -       || local/file  ||   || local/dir/file || -
 || -             ||

 || ERROR-4       ||
 || trunk -r || ERROR-2 || local/file  ||   || local/dir/file ||
 EXCEPTION-1 || EXCEPTION-1   ||


 And for `cp [-r] X local/missing`, where `local` exists but `missing` does
 not:

 =||= command =||= FILECAP      =||= DIRCAP/file       =||=  =||=
 PARENTCAP/dir         =||= DIRCAP            =||= DIRCAP_ALIAS:     =||=
 || cp       || -             || local/missing      ||   || ERROR-4b
 || -                  || -                  ||
 || cp -r    || -             || local/missing      ||   ||
 local/missing/file     || -                  || -                  ||
 || cp -R    || -             || local/missing      ||   ||
 local/missing/file     || -                  || -                  ||
 || 1.10     || local/missing || local/missing      ||   || ERROR-4
 || ERROR-4            || ERROR-4            ||
 || 1.10 -r  || EXCEPTION-3   || local/missing/file ||   ||
 local/missing/file     || local/missing/file || local/missing/file ||
 || trunk    || local/missing || local/missing      ||   || ERROR-4
 || ERROR-4            || ERROR-4            ||
 || trunk -r || EXCEPTION-3   || local/missing/file ||   ||
 local/missing/dir/file || EXCEPTION-1        || EXCEPTION-1        ||


 * EXCEPTION-1: `build_graphs()`, `NoneType has no attribute startswith`
 * ERROR-2: you must specify a destination filename
 * EXCEPTION-3: `put_file()` line 156, `name` is None but precondition
 requires `isinstance(unicode)`
 * ERROR-4: cannot copy directories without --recursive
