This patch adapts the format identifiers to produce output which stays in
the same column by in essence increasing the width by one to the right.
These formatting problems had been observed in test runs with DCCP, at
various different speed dimensions (Kbps, Mbps, Gbps) - it is 1 space.
No principal changes, just "neater" output; the rest of the patch addresses
some typos.
Format update and some typo (comments) fixes
