I've been testing Roland's OS/Net ksh93 2006-08-05 test binaries and I think that there is a bug which prevents the TAB and TABTAB expansion to work for the new ~(E) pattern feature. If I have the following files in my cwd aa.c ab.c aab.o and type echo ~(E)^a.*c and then TABTAB I insert a tab character but no list of choices appears
