[Bug-tar] -F script from the docs not working on cygwin?

[Hugh Sasse]

I've just had this failure on cygwin 

address@hidden ~/fresnel
$ tar -c -L$((1024 * 1024 * 3)) -f win_users_split.tar -F ./new_volume 
./win_users.tar.bz2
Preparing volume 2 of win_users_split.tar.
./new_volume: line 12: echo: write error: Broken pipe
  22711 [sig] tar 3812 C:\cygwin\bin\tar.exe: *** fatal error -
adlist_ix -1
Hangup

address@hidden ~/fresnel
$ tar -c --multi-volume -L$((1024 * 1024 * 3)) -f win_users_split.tar -F 
./new_volume ./win_users.tar.bz2
Preparing volume 2 of win_users_split.tar.
      9 [sig] tar 2744 C:\cygwin\bin\tar.exe: *** fatal error -

address@hidden ~/fresnel


with the new_volume script as 
address@hidden ~/fresnel
$ cat new_volume
#!/bin/bash
echo Preparing volume $TAR_VOLUME of $TAR_ARCHIVE.

name=`expr $TAR_ARCHIVE : '\(.*\)-.*'`
case $TAR_SUBCOMMAND in
-c)       ;;
-d|-x|-t) test -r ${name:-$TAR_ARCHIVE}-$TAR_VOLUME || exit 1
    ;;
*)        exit 1
esac

echo ${name:-$TAR_ARCHIVE}-$TAR_VOLUME >&3


address@hidden ~/fresnel
$

i.e lifted from the manual, one folded line straightened out and 
when that failed changed from /bin/sh to /bin/bash

It always fails on that last echo statement.  Should I expect this on 
cygwin?  

(for now I've solved the problem with

$ tar -c --multi-volume -L$((1024 * 1024 * 3)) -f win_users_split1.tar -f 
win_users_split2.tar -f win_users_split3.tar -f win_users_split4.tar 
./win_users.tar.bz2

so I don't need a workaround at the moment. I'm interested in whther this
is a known problem or not.)
