I'm not putting attributes of a results table into $_REQUEST, I'm  
keeping track of what the current $_REQUEST is. The idea is that you  
specify "show me all users with a last name containing the string  
'Smith'". This gets sent (using a GET form) as something like  
"q=site_user_list&fields=last_name&string=Smith". It displays a list  
of all the users with a last_name field of 'Smith', and has columns  
which you can sort on. If $_REQUEST is not serialized back into the  
URL automatically in tablesort_get_querystring(), the URL that the  
column headers would go to would be things like  
"q=site_user_list&sort=last_name&order=desc",  
"q=site_user_list&sort=first_name&order=desc", etc, instead of what  
they should have:  
"q=site_user_list&fields=last_name&string=Smith&sort=last_name&order=des 
c", etc. So if $_REQUEST wasn't serialized back into the URL, when  
you tried to change the sort order of the display, the parameters  
that restrict what is being shown would be lost. I imagine that's  
also the reason this is done for pager_get_querystring().
