+By default, shell history that is read in from files is split into
+words on all white space. This means that arguments with quoted
+whitespace are not correctly handled, with the consequence that
+references to words in history lines that have been read from a file
+may be inaccurate. When this option is set, words read in from a
+history file are divided up in a similar fashion to normal shell
+command line handling. Although this produces more accurately delimited
+words, if the size of the history file is large this can be slow. Trial
+and error is necessary to decide.
