I have reported this to Dick Koch and he is looking at the issue.
Interestingly, these files can be opened and saved without any
problems using BBEdit. It turns out that any file that behaves this
way can be opened and saved over the "misbehaving" file via "Save
As..." (this replaces the bad file). This has been an easy workaround
for me until Dick finds out what is going on.
