Bug#358164: libedit2: adding \n incrementally with read/write history

[Akira TAGOH]

Package: libedit2
Version: 2.9.cvs.20050518-2.2
Severity: normal

a linefeed is always increased whenever
read_history/write_history is invoked. please try an
attached code. on GNU readline, foo.his has only "input
word" in the line. but on libedit, three \012 will be added
after "input word" so that read_history/write_history is
invoked three times intentionally.
