Actually --header output gives us original parents. Rewritten parents
(available with --parents) include also grafts and shallow clone grafts.
For parse_commit we want --parents, for parse_commits we don't want it
because --parents affects --full-history.
The problem is that we cannot detect if git-rev-list was called with
--parents and commit is root commit (parentless), or we didn't use
--parents option.
In few other places we pass options specifying subroutine behavior
as hash after all other requred parameters, e.g.
esc_html($line, -nbsp=>1),
parse_ls_tree_line($line, -z=>1),
git_print_log($co{'comment'}, -final_empty_line=> 1, -remove_title => 1);
In this case it wouldn't work (unless we pass reference to array,
via parse_commit_text( [ <$fd> ], -parents=>1);
Perhaps it would be better to use reference to hash of options as _first_
parameter, e.g. parse_commit_text({-parents=>1}, <$fd>);, and use something
like if (ref($[0]) == 'HASH') { $opts = shift @_; } to get options.
So for now gitweb might not show what we want in very rare cases of
repositories with grafts or shallow clones.
But apart from this small matter, this series is excellent work. Thanks!
