[Eeglablist] Error in pop_epoch command line

[Makoto Miyakoshi]

Dear Kelly, Ramon, Arno,

Kelly's event names contain space in the end so that the all the event
names has 4-letter length. I think this is the cause of the problem. Most
likely, some of Matlab functions handles space as space (I guess the one
Kelly used does), while others not...

Kelly, my advice is that you don't use space in this way. It can cause
troubles like this. Instead of using '510 ', you should choose '5100'. For
the same reason, you don't want to use any weird character like %&*^()~+|
it'll cause troubles as well (the same applies to path names, variable
names, and file names!)

Makoto
