I thought that might be the case, but the following also throws the same 
backreference error:

re = 
'(sun)(mon)|(mon)(tue)|(tue)(wed)|(wed)(thu)|(thu)(fri)|(fri)(sat)|(sat)(sun)';
s = REReplaceNoCase(s, re, '\1,\2', 'all');    // adjacent weekdays

Ah... I think I see what the problem is.  If the match is SatSun then I'd 
need to use \13 & \14.  I'm not sure I know how to deal with that.
