[Eeglablist] ADJUST fails when #components=/=#channels

[Makoto Miyakoshi]

Dear John and Wanze,

I don't use SASICA so no advice there, but

fake EOG channels.

Oh yeah I always use AFp9 as left canthus (i.e., left horizontal) EOG.
1-2cm difference is trivial considering accuracy of our standard procedure,
particularly if you don't use channel location digitizer.
