Did some more investigation - the problem doesn't occur if I edit the
file in CMD.EXE, using the EDIT text editor, nor does it occur if I
edit the file using regular Windows apps like Notepad, WordPad, etc.
A driver problem is definitely a possibility (I'm already suspecting
the NVIDIA nForce chipset drivers), and will look into it.

Some details of my hardware which might help: AMD Athlon X2 4200+
dual-core processor,  Seagate 300MB SATA hard drive, 1 GB dual-channel
RAM, NVIDIA nForce chipset (as noted above), Asus A8N5X motherboard.
