The "29" is a field-width specification. The % is the conversion
specifier (called the "control letter" in awk's docs).

mawk seems to require an argument for both the %b and %29%, but then
does not actually _use_ it if supplied (%29 and % are apparently treated
as separate specifiers, and so require two unused arguments). This
strongly suggests a deficiency in mawk, to me.

There is no %c at the end, there is only c (the preceding % is part of
the %29% that has already been explained).
