 Chet: for reasons unexplained calls to read_history_range at

219           result = read_history_range (filename, history_lines_in_file, -1);

return more and more records (77824 is above my HISTFILESIZE):

1: history_lines_in_file = 77824

the loop at histfile.c:269 in read_history_range is the one that hangs.
