Bash Version: 3.0
Patch Level: 0
Release Status: release

Description:
        I am submitting a new test for bash.  It checks that the LINENO
        variable is updated correctly when here-documents are processed.

        This test is useful because bash 2.0 contained a bug.  It would
        not increment LINENO when an "unquoted" here-document contained
        a backslash-newline continuation.  This behavior was fixed in 3.0,
        but there is no test in the test suite to verify that the behavior
        remains correct.  As this bug has caused us some problems (when using
        Gnu's autoconf!), I wrote a test.

Repeat-By:
        You can cause bash 2.0 to show the problem by running:

                #! /bin/bash

                cat <<EOF
                Line 1 \
                Line 2
                EOF

                echo Should be 8: $LINENO

        This script will output "Should be 8: 7" in bash 2.0.

Fix:
        The following is a diff listing to install the files
        tests/lineno.right, tests/lineno.tests, and tests/run-lineno.
