Hi

I've just discovered that the command line is not always displayed
correctly. This happens both in the 'normal' window you get when clicking on
the cygwin icon, or in an xterm. I first thought it was related to the
setting of PS1. However, I tried to put PS1 the same on a debian system, and
there is no problem there. Also, the same happens after
PS1='$ '


Here is how to reproduce it:

startxwin.bat and click on the xterm with the bash window. Or click on your
cygwin icon. I didn't set PS1 or so, so the window just looks like
--------------------------
kris AT petnt1 ~
$
--------------------------

Now type a non-existing command and put it in the background. My display
looks like

--------------------------
kris AT petnt1 ~
$ b&
[1] 269

kris AT petnt1 ~
$ bash: b: command not found
--------------------------

Note that the prompt *preceeds* the bash error message.

Now type a few characters (at least 4). They will be displayed in the first
column just below "bash :".

--------------------------
kris AT petnt1 ~
$ b&
[1] 269

kris AT petnt1 ~
$ bash: b: command not found
Here is some text
--------------------------

Then press Ctrl-A to go to the start of the line. The prompt will overwrite
the first 2 characters of what you just typed.

--------------------------
kris AT petnt1 ~
$ b&
[1] 269

kris AT petnt1 ~
$ bash: b: command not found
$ re is some text
--------------------------
Then typing again will shift the remaining characters, but still not display
the ones that were just erased. Only a Ctrl-L saves the day.


Clearly the bash prompt should be displayed *after* the error message.


This happens on my NT 4.0 sp6 system with a fresh cygwin, and on my XP sp1
system with a cygwin release that is slightly older (cygwin.dll 1.5.10-3).
Both have GNU bash, version 2.05b.0(1)-release (i686-pc-cygwin).

(sorry for such a long message for such a small thing).

(please reply explictly to me as I'm reading this mailing list via the web)

Thanks!
