No, the above example callsite says "Do I need to fill either 'age' or
'age_string'", and is followed by actually filling this info.

Currently the code flow WRT. project information goes like this:

  git_get_projects_list()
  # this fills some of project info; what is filled depends on whether
  # $projects_list is a file with list of project or directory to scan
  filter_forks_from_projects_list()
  # this does not use project info
  fill_project_list_info()
  # this fills all the rest of project info on reduced list
  search_projects_list(<search data>)
  # this uses some of project info

After 2/5 the code goes like this:

  git_get_projects_list()
  # this fills some of project info; what is filled depends on whether
  # $projects_list is a file with list of project or directory to scan
  filter_forks_from_projects_list()
  # this does not use project info
  fill_project_list_info(<search data>)
  # this fills the rest of project info required for search on reduced list
  search_projects_list(<search data>)
  # this uses some of project info
  fill_project_list_info()
  # this fills all the rest of project info on further reduced list

If @fill_only is empty, it means for fill_project_list_info to fill
all the data, if it is not empty it means that those fields needs to
be filled.

The code of fill_project_list_info goes like this

  if (do we need to fill 'age' or 'age_string'?) {
    fill 'age' and 'age_string'
  }
  if (do we need to fill 'desc_long' or 'descr'?) {
    fill 'descr_long' and 'descr'
  }
  if (we are interested in 'ctags' &&
      do we need to fill 'ctags'?) {
    fill 'ctags'
  }
  ...
