GNU gdb 6.6-debian
This GDB was configured as "i486-linux-gnu".

GNU C Library stable release version 2.6, by Roland McGrath et al.
Compiled by GNU CC version 4.1.3 20070629 (prerelease) (Debian 4.1.2-13).

>Description:
When I use gdbtui with DOS style(CRLF) source file, it shows empty lines between every source lines.
So the line numbers do not match the source lines.

gdbtui should ignore CR and not show empty lines.
>How-To-Repeat:
It always happen when I debug the source file which has DOS style end of line.
>Fix:
gdbtui should not show empty lines.
