Hi,

In the m4 documentation web page, for example at 
https://www.gnu.org/software/m4/manual/m4.html#Comments 
<mailto:[email protected]>, the character used for an opening single quote 
displays incorrectly.  Here is a snapshot:

I'm pretty sure what is meant is that the same character is used both 
before and after *quoted text* above.  But what appears is a slanted 
tick and then a straight tick.

I think this should read:

    $m4

    'quoted text' # 'commented text'
    ...


If I disable the style sheet I still see them wrong, so it's not a css 
thing:



Also this is not dependent on browser, i.e. Firefox and Chrome both 
display this the same.
