Subject: patch for doscan.c

When you open a file in binary mode, fscanf does not work correctly.
It doesn't consider '\r' as whitespace, so it fails on files with
the usal MSDOS "\r\n" end of line. The following patch should help.
If you want to try it, please let me know, whether it worked or not.

doscan.c is in libsrc/c/io
