I favor this change: it is simple, it restores old functionality, and it supports useful behavior. By the way, this general topic has been discussed recently by the Open Group. The question was whether standard commands like "od -" are required to read a file named "-", or whether they are allowed to read stdin instead. The consensus was that POSIX does not specify the behavior here, and that an implementation of "od -" is allowed to either read a file named "-", or to read standard input. While this conclusion doesn't directly affect Automake (which isn't standardized yet :) it does suggest that "-" should either refer to standard input, or to a file named "-". Personally I think the former is more consistent, as it is the GNU style (used in coreutils).
