 1.1 History Expansion
 =====================
 
 The History library provides a history expansion feature that is similar
 to the history expansion provided by `csh'.  This section describes the
 syntax used to manipulate the history information.
 
    History expansions introduce words from the history list into the
 input stream, making it easy to repeat commands, insert the arguments
 to a previous command into the current input line, or fix errors in
 previous commands quickly.
 
    History expansion takes place in two parts.  The first is to
 determine which line from the history list should be used during
 substitution.  The second is to select portions of that line for
 inclusion into the current one.  The line selected from the history is
 called the "event", and the portions of that line that are acted upon
 are called "words".  Various "modifiers" are available to manipulate
 the selected words.  The line is broken into words in the same fashion
 that Bash does, so that several words surrounded by quotes are
 considered one word.  History expansions are introduced by the
 appearance of the history expansion character, which is `!' by default.
