Bash Version: 3.1
Patch Level: 16
Release Status: release

Description:
        Inline comments worked in earlier versions of bash (e.g. 3.0).
They seem to cause errors, now. I could not find any comment on this in
the changelog.

Repeat-By:
        use "$( #comment )" in a bash script to generate an inline comment.
        this will cause the "unexpected EOF while looking for matching
`)'" error.
