Bad channels in evoked data

When using fiff_read_evoked_all.m, does the 'info.bads' field correspond
to the union of bad channels from all runs that were used to create the
average? In other words, if a channel is bad only in one run, will it
show as a bad channel in the average?

The bad channel list in the grand average will be that of the first
run included into the grand average, not the union of bad channel
lists in all component files.
