Dunno, would have to test more. (*.ob2? Can't remember offhand.)
Remember, this is DOSEMU x86-64, so it's not as good as the
traditional 32-bit one. So more than likely it's their "bug" (or lack
of support).

Honestly, I don't care for 64-bit (and don't "need" it personally, but
it is fast becoming ubiquitous), but for whatever reason I thought I
should test DOSEMU there for a while, for curiosity, to see how
compatible it is.

Perhaps I shouldn't bug you with comments when tested in such an
"unstable" environment. Well, I have 32-bit DOSEMU on my other
computer, so I guess I should install DJGPP Emacs there too, for
reference. (Or get/make another jump drive.)

No because there is no traceback. I didn't mean it "crashes", it may
not at all, but it definitely closes the whole "DOS in a box" terminal
window, which means something somewhere is aborting it. It may just be
some 16-bit code incompatibility (most likely).

Well, it's not important, and it's an easy fix (just turn it on!). I
just wanted to mention it since it seemed out of place (Pascal works
by default, Modula-2 doesn't). Seems too trivial to report it.

This is what I always see people doing, but it always seems kludgy to
me.

This is what I meant. I guess I was naive to think it would
"magically" find any font lock *.el files and magically know when to
highlight. In TDE, the *.shl (syntax highlight file) has file name
extensions listed in it for each language, so it always knows which
are valid. But perhaps somebody somewhere (somewhat doubtful) thought
*.mod was "too generic" (Amiga sound module?).

Modula-2, I think, but possibly others too. This is more than likely
just a built-in limitation of the way Emacs handles font lock. Or
perhaps it's just a corner case that nobody worries about. Some
languages do indeed let you use \ as an escape, but others don't, so
it's only incorrect some of the time.

Heh, yes, I know. I could also (re)grab enwik8 and copy it 5x. Hmmm, I
forgot Project Gutenberg had some interesting documents that would fit
the bill. (I just grabbed one that was 5.9 MB, yow, cabbage-brained!)

(Hope this wasn't too much of wasting your time.)
