+This should be set to the address of a function that takes two arguments:
+a @code{char *} (@var{string}) and an integer index into that string (@var{i}).
+It should return a non-zero value if the history expansion starting at
+@var{string[i]} should not be performed; zero if the expansion should
+be done.
+It is intended for use by applications like Bash that use the history
+expansion character for additional purposes.
+By default, this variable is set to NULL.
