That is exactly what Ada.Text_IO.Text_Streams gives you. (I can't
imagine an implementor doing something else...)

Probably your problem is that the OS is eating the <CR>s from Standard
Input, and Ada never sees them. I would expect that you would find this
behavior with any file type that read from the Standard Input handle.

In the mail handling code I've written, I simply assume that the <CR>s
are where they are supposed to be by the RFCs, and put them back in as
needed. Mail that violates RFCs is almost certainly spam anyway; don't
worry about that causing problems, just dump it.

(Bare <CR>s and <LF>s are prohibited by the mail and MIME RFCs anyway,
no mail should have such characters, and what mail servers do with such
mail is undefined. <CR>s paired with <LF>s can always be inserted [and
should be inserted] if you get any bare line ending characters.)
