Extracted for ease of review from a previous (pending) diff about
refactoring gotweb_render_index.

commit 0ceb1b9e49ae865b84f237977d7edbcaa9697161
from: Omar Polo <op@omarpolo.com>
date: Tue Nov 22 11:00:49 2022 UTC
 
 gotwebd: use prev_disp to decide when to we've reached max_repos
 
 instead of hardcoding d_i - 2 and so expecting only "." and ".." as
 skipped entries, use t->prev_disp that is the number of repositories
 traversed until now (both skipped due to the pagination and the ones
 actually rendered.)
