This goes beyond my capabilites :-/

I put a breakpoint in x_new_font, and got this result:

Breakpoint 6, x_new_font (f=0x86c1678, fontname=0x86af3a0 "-xos4-terminus-medium-r-normal--17-123-100-100-c-90-iso8859-1") at xterm.c:7848
(gdb) n
(gdb) p *fontp
$11 = {
  font = 0x86c1e28, 
  font_idx = 0, 
  name = 0x86c1d50 "-xos4-terminus-medium-r-normal--17-123-100-100-c-90-iso8859-1", 
  full_name = 0x86c1de0 "-xos4-terminus-medium-r-normal--17-123-100-100-c-90-iso8859-1", 
  charset = 0, 
  size = 9, 
  height = 16, 
  space_width = 9, 
  average_width = 9, 
  vertical_centering = 0, 
  encoding = "\000\377", '\0' <repeats 126 times>, '\001' <repeats 127 times>, 
  baseline_offset = 0, 
  relative_compose = 0, 
  default_ascent = 0, 
  font_encoder = 0x0
}

So the frame's default font width is 9 pixels.

But when I contine and get to the place where an "A" is inserted in the header line,
I get this font info for the "A" character:

(gdb) 


So somewhere along the road, something has selected a different font (width 8)
for the characters in the header line -- and in the text area of the window,
but the align-to uses the default frame font of width 9 (that's what it has to do).

How can this happen?



To reproduce, get the above font installed, and put this in .Xdefaults:

Emacs.font: -*-terminus-medium-r-*-*-17-*-*-*-*-*-iso8859-1

Then run

emacs -Q ~/tmp/foo.ses

Now hit M-o a few times to add some columns.

and type 1 RET 2 RET 3 RET to insert some data in the sheet.
