I think it's because GDB counts characters and then lseeks to the
point it thinks it should display. If the library's text-mode I/O
converts \r\n to \n, this seeks will only work reliably in binary
mode, since most DOS/Windows libraries don't seek to the correct place
(the only exception from this rule I know of is the DJGPP library).
