# Test which attempts to repeat examples of formatted output
# from "C a reference manual" by Harbison and Steele.
#
# In the second series of outputs formats of a type "%5%" are skipped
# since my old copy of H&S explicitely requires padding ("...%05% will
# print 0000%..."), whereas Standard says "...the complete conversion
# specification shall be %%".
