Yes, that's how the DJGPP port of the Readline library works: it does
file I/O in text mode.

It was a deliberate decision to leave the I/O at text mode, yes.

Personally, I'm not happy about it.  The redirection to a Unix-style
file is a nuisance, but I'm concerned about the more serious case
where a non-printable character such as Ctrl-Z sneaks into the history
file due to some peculiar set of commands.

At the time, I submitted patches to Readline to use binary I/O for
history files, but those patches did not make it into the current
sources.  Since the problematic cases are marginal, I didn't protest
too vociferously.
