I am not sure if always sorting the categories alphabetically is a severe
enough restriction, but if it was, you can use @project_list_categories
array that disables the feature when empty and otherwise enumerates the
categories in order.  Just an idle thought.

Could you clarify this bit?

It is not very clear to me how this subset selection happens.  As far as I
can see, the user does not choose the category to view, but lets the usual
page limiting to decide at which project to start and stop placing on the
page, and only show the ones in the same category as the one that happened
to be the first on the page.

While I think both the introduction of "git_get_project_config_or_file"
which is a generalized interface usable between description and the new
feature and the refactoring of project_list_body into a seprate function
"print_project_rows" is a good idea, the patch would have been much easier
to read if these preparatory refactoring steps (without any new feature)
were done as a separate patch followed by the main patch to introduce the
new feature.
