Problems when using iswitchb-mode - Probably a bug

[Jon Davis]

Hi,

In GNU Emacs 21.3.50.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2002-09-02 on gnu
configured using `configure --prefix=/home/jd'

Important settings:
  value of $LC_ALL: nil
  value of $LC_COLLATE: nil
  value of $LC_CTYPE: nil
  value of $LC_MESSAGES: nil
  value of $LC_MONETARY: nil
  value of $LC_NUMERIC: nil
  value of $LC_TIME: nil
  value of $LANG: en_US
  locale-coding-system: iso-latin-1
  default-enable-multibyte-characters: t


I have encountered problems when using iswitchb-mode.

Steps to reproduce the bug:

1. Create 2 files named `test1.txt' and `test2.txt'.

2. Visit the files `test1.txt' and `test2.txt'.

3. Enable Iswitchb mode. E.g. type `M-x iswitchb-mode' (without quotes)

4. Try to switch between buffers by typing:

   4.1  `C-x b',

    Result: The list of buffer containing `test1.txt' and `test2.txt' 
is displayed.

   4.2  Then type `txt' (without quotes)

   Expected result: a list of buffers that match the substring `txt' 
(without quotes) should be displayed; the list should include the 
buffers test1.txt and test2.txt.

   Actual result: an empty buffer list is displayed.

   4.3 You can further try to delete some or all of the letters in the 
`txt' substring or add other letters.  Iswitchb mode should continuously 
display a list of buffers that match the substring that was typed. 
However an empty list is always displayed instead.
