Bash does not wrap long lines correctly

Ksh is my default shell, but I want use the bash shell since its convenient to me.

When I type a long command line in a terminal, it does not wrap to the next line when I reach the end of the line and it wraps onto the same line, overwriting my prompt and the rest of what I typed.

Code:

$ echo $SHELL
  /bin/ksh
  $ ve and accept responsve and accept responsve and accept responsve and accept responsve and accept responsve and accept responsve and accept responsve and accept responsve and accept responsve
  $ bash
   ash-3.2$ sponsve and ae asponsve and ae asponsve and ae asponsve and ae asponsve and ae asponsve and ae asponsve and ae
  bash-3.2$ stty -a
  speed 38400 baud; rows 44; columns 120; line = 0;
  intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>; swtch = <undef>; start = ^Q;
  stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0;

  bash-3.2$ echo $TERM
  xterm
  bash-3.2$ export TERM="vt100"
  bash-3.2$ echo $TERM
  vt100
   ae and accept responsve and ae and accept responsve and ae and accept responsve and ave and ae and accept responsve and
  bash-3.2$

I searched in the Unix and internet, all problem solved by modifying the customized PS1 command but I don't have any customized prompt I am using default one.

WRAP-AND-SORT(1)					      General Commands Manual						  WRAP-AND-SORT(1)

NAME

       wrap-and-sort - wrap long lines and sort items in Debian packaging files

SYNOPSIS

       wrap-and-sort [options]

DESCRIPTION

       wrap-and-sort  wraps the package lists in Debian control files. By default the lists will only split into multiple lines if the entries are
       longer than 80 characters. wrap-and-sort sorts the package lists in Debian control files and all .install files. Beside that  wrap-and-sort
       removes trailing spaces in these files.

       This  script should be run in the root of a Debian package tree. It searches for control, control.in, copyright, copyright.in, install, and
       *.install in the debian directory.

OPTIONS

       -h, --help
	      Show this help message and exit.

       -a, --wrap-always
	      Wrap all package lists in the Debian control file even if the entries are shorter than 80 characters and could fit in one line line.

       -s, --short-indent
	      Only indent wrapped lines by one space (default is in-line with the field name).

       -b, --sort-binary-packages
	      Sort binary package paragraphs by name.

       -k, --keep-first
	      When sorting binary package paragraphs, leave the first one at the top.  Unqualified debhelper(7) configuration files are applied to
	      the first package.

       -n, --no-cleanup
	      Do not remove trailing whitespaces.

       -d path, --debian-directory=path
	      Location of the debian directory (default: ./debian).

       -f file, --file=file
	      Wrap  and sort only the specified file.  You can specify this parameter multiple times.  All supported files will be processed if no
	      files are specified.

       -v, --verbose
	      Print all files that are touched.

AUTHORS

       wrap-and-sort and this manpage have been written by Benjamin Drung <bdrung@debian.org>.

       Both are released under the ISC license.
