Comment (by glynn):

 Replying to [ticket:929 hamish]:

 > I'm not decided what to do about reading from stdin. I suspect I'll have
 to drop the east_north=x1,y1,x2,y2,xn,yn,... option in favor of an input
 file containing points to be transformed because the parser insists on two
 values, and "-,-" if given is read as -0,-0. Well, I guess I could have
 strcmp() test for "-,-" but it's a bit silly.
 > I'd rather not add another flag to direct the input.
 > any ideas?

 Don't try and make one option do different things; use a separate option
 for reading from a file (use file=- for stdin rather than a flag).
