Subject: 25.1; Fonts used by default in Info
Date: Mon, 3 Oct 2016 08:48:51 -0700 (PDT)

The fonts used (on MS Windows, at least) by default, for Info, are
these:

* For text in general:

  uniscribe:-outline-Courier
  New-normal-normal-normal-mono-17-*-*-*-c-*-iso8859-1 (#x52)

* For text enclosed in ‘...’:

   gdi:-outline-Courier-normal-normal-normal-mono-17-*-*-*-c-*-iso8859-1
   (#x65)

The latter comes from the default value of face `Info-quoted', which
specifies only the family (as courier).

Why use, by default, two **slightly** different looking fonts?  They are
not different enough to make ‘...’ very noticeable.  Nor are they the
same.  What's the point of this choice?


In GNU Emacs 25.1.1 (x86_64-w64-mingw32)
 of 2016-09-17 built on LAPHROAIG
Windowing system distributor 'Microsoft Corp.', version 6.1.7601

The point is exactly to have a different face for symbols.

I don't disagree with that point.

What's the point of using family Courier for one and Courier New for
the other?  That's the question.  Doesn't seem like a great choice.

I believe we don't specify Courier, it's just what Emacs picks up on a
typical Windows machine when we ask for a "Monospace Serif" font.  See
the definition of the Info-quoted face in info.el.

Hm. What I see is that we specify the "courier" family, not that we ask
for a "Monospace Serif" font:

(defface Info-quoted '((t :family "courier"))
  "Face used for quoted elements.")

I know nothing about such things, but it seems odd that MS Windows
creates font Courier New, and seems to use it by default quite a bit,
and yet we tell it to use family "courier", and it ends up using
font Courier (if available), not Courier New.

I think maybe you are saying that there is no good way to make
the two use the same font by default.  So be it, if so.

[I'd suggest using two fonts that are more different, by default.
For one thing, that would make clear to users that a face is involved.
Or if there is no policy to avoid color, I would use the same font
but a foreground color different from the default (black).]

That's strange: it's "courier" in 25.1, but the release branch says
fixed-pitch-serif, and the change was in May, so should have been in
the released Emacs 25.1.

Nicolas, can you shed some light on this?

It chooses the first font that satisfies the request.

That's what we do, except that this somehow didn't get into Emacs
25.1.

It was installed after the release.

Oh, "git show" surprisingly shows the original commit date for
cherry-picked commits, so I became confused.

Thanks.

It shows the author date.  If you want to see the commit date use
--pretty=fuller.

Yes, but it never says that, nor attempts to display both dates when
they are different.  How unhelpful.

> If you want to see the commit date use --pretty=fuller.

Thanks, the moment I understood the issue I did that in my
~/.gitconfig, so I won't ever need to remember this quirk.

I believe that this was fixed in:

commit 36906806ccfc0e53f1d8c365ab0d7151288b7833
Author: Paul Eggert <eggert <at> cs.ucla.edu>
Date:   Fri May 13 13:30:33 2016 -0700

    Improve display of tex-verbatim and Info quoted

Which was part of Emacs 26.1.  I'm therefore closing this bug as such.

Best regards,
Stefan Kangas
