[HACKERS] Small issue in online devel documentation build

When consulting the online "devel" documentation, for instance for 
"pgbench":
    https://www.postgresql.org/docs/devel/static/pgbench.html

Unordered lists <ul> are shown in bold, as can be seen in the -M option 
and in the description of random functions. This is because "ul" is in 
class "c2" in the html:
    <ul class="itemizedList c2"> ...

I cannot reproduce this when generating html for head, so I gather that 
the web-site doc generation must be based on a different transformations.

My point is that some xsl file should be fixed somewhere, probably, to 
avoid that.
