bug#23292: 24.5; Combining characters do not reliably combine |

Combining characters often do not render combined in emacs 24.5.
For example, the combining short solidus overlay (0x337, o̷) appears
following the character it's meant to combine with---although they are
both highlighted together and so forth.
cf. https://i.imgsafe.org/8369941.jpeg for a visual reference.
This seems similar to bug 17261, but both characters are from the same
font, DejaVu Sans Mono.
describe-char for the combined (but separately rendered) o̷:
---------------------------------------------------------------------------
position: 14 of 70 (19%), column: 12
character: o (displayed as o) (codepoint 111, #o157, #x6f)
preferred charset: ascii (ASCII (ISO646 IRV))
code point in charset: 0x6F
script: latin
syntax: w which means: word
category: .:Base, L:Left-to-right (strong), a:ASCII,
l:Latin, r:Roman
to input: type "C-x 8 RET HEX-CODEPOINT" or "C-x 8 RET NAME"
buffer code: #x6F
file code: #x6F (encoded by coding system utf-8)
display: composed to form "o̷" (see below)
Composed with the following character(s) "̷" using this font:
xft:-PfEd-DejaVu Sans Mono-normal-normal-normal-*-13-*-*-*-m-0-iso10646-1
by these glyphs:
[0 1 111 82 8 1 7 7 0 nil]
[0 1 823 703 8 0 8 8 1 nil]
Character code properties: customize what to show
name: LATIN SMALL LETTER O
general-category: Ll (Letter, Lowercase)
decomposition: (111) ('o')
---------------------------------------------------------------------------
describe-char for the combining short solidus overlay by itself:
---------------------------------------------------------------------------
position: 619 of 1008 (61%), column: 42
character: ̷ (displayed as ̷) (codepoint 823, #o1467, #x337)
preferred charset: unicode-bmp (Unicode Basic Multilingual Plane
(U+0000..U+FFFF))
code point in charset: 0x0337
script: latin
syntax: w which means: word
category: ^:Combining
to input: type "C-x 8 RET HEX-CODEPOINT" or "C-x 8 RET NAME"
buffer code: #xCC #xB7
file code: #xCC #xB7 (encoded by coding system utf-8)
display: composed to form "̷" (see below)
Composed by the rule:
(TAB ?̷ TAB)
The component character(s) are displayed by these fonts (glyph codes):
̷: xft:-PfEd-DejaVu Sans
Mono-normal-normal-normal-*-13-*-*-*-m-0-iso10646-1 (#x2BF)
See the variable `reference-point-alist' for the meaning of the rule.
