I'm very sorry. There were some bugs sneaked in the patchst
and I missed them by running tests on unclean tree.

I'm posting 3 additional patches.
[12/14] Do not make extra call to lv_add_user_seg()
[13/14] lvconvert should check first_seg(original_lv)
[14/14] lvconvert help message wasn't fixed to '--wait'

This patch is:

[12/14] Do not make extra call to lv_add_user_seg()
          Without this, lv->segs_using_this_lv will have
          duplicated entry and find_mirror_seg() will fail.
          VG validator will detect it and so most commands
          will not work.
