I might as well throw in a desire for comments.
Currently I add comments to svn:ignore by begining a line with # and
assuming no file will actually be called "# Generated by Make".
Sloppiness aside (it's effective, no reason to call it sloppy), the
ability to add comments in-line is still desireable. Adding an option
"*" in addition to "!" would allow C-style-looking comments:
somefile /* this is only required by windows and can be easily
regenerated */
