[Console] replaced fgets by stream_get_line in DialogHelper

fabpot · fabpot · commit 3a5d508766f0 · 2011-07-07T09:41:45.000+02:00
Problem with fgets is that false means two things: an error or the end of the stream.
That's ok for STDIN, but it becomes a problem when using another stream (in a unit test for instance).
