阿部です。

Emacs21から、正規表現に
>`\{N,M\}'
>     is another postfix operator that specifies an interval of
>     iteration: the preceding regular expression must match between N
>     and M times.  If M is omitted, then there is no upper bound and if
>     `,M' is omitted, then the regular expression must match exactly N
>     times.
が追加されたため、このパッチのようにしないと以下のようになります。

====例====
ARGF.each do |line|
<<<ここでTABを押すと "Unmatched \\{" と出る>>>
==========

ただ、これで他に影響がでないかどうか、追跡できてません。
取り急ぎ報告まで
