+	multi-tty Emacs.

+	* erc-log.el (erc-log-standardize-name): New function that returns
+	a filename that is safe for use for a log file.
+	(erc-current-logfile): Use it.
+
+	* erc.el (erc-startup-file-list): Search in ~/.emacs.d first,
+	since that is a fairly standard directory.
+	(erc-select-startup-file): Re-write to use
+	convert-standard-filename, which will ensure that MS-DOS systems
+	look for the _ercrc.el file.
