Bash Version: 2.05b
Patch Level: 0
Release Status: release

Description:
        When expanding variables in here-documents at the beginning
        of a line, a leading TAB character is dropped.
        If the var expansing is not at the start of the line,
        the TAB does not get dropped.
        Version 2.05 does not exhibit this bug.

Repeat-By:
        ee="    xy"             # contains leading TAB character
        cat << EOF | od -c
        $ee
        EOF
        # the TAB character is missing from the here document
