My apologies, i accidentally used a non -Q instance to test 
this. :-/ In a -Q instance, it turns out that DejaVu Sans Mono 
(Book) /does/ compose visually:

Composed with the following character(s) "̷" using this font: 
 xft:-unknown-DejaVu Sans 
 Mono-normal-normal-normal-*-13-*-*-*-m-0-iso10646-1 
by these glyphs: 
 [0 1 111 82 8 0 8 8 1 nil] [0 1 823 703 0 0 8 8 1 [-8 0 0]] 

Sorry!

However, Inconsolata-g definitely doesn't compose visually.

Interestingly, when i use `describe-char' on the 'o', i'm told 
that the glyph is sourced from Inconsolata-g, but when i use it on 
the '/', it tells me it's sourced from Gentium ....
