APIs descriptions should describe the purpose of the function, its
parameters and return value. While working  on man pages implementation,
I noticed mismatches in the  descriptions of few APIs.  This patch
changes the description of these APIs, making them consistent with the
man pages:

 - tep_print_num_field()
 - tep_print_func_field()
 - tep_get_header_page_size()
 - tep_get_long_size()
 - tep_set_long_size()
 - tep_get_page_size()
 - tep_set_page_size()
