Right, but look at the context.

option, and then print statistics and exit.
.TP
\c
This mode is useful for generating statistics about network quality.
Note that each running instance of
.B mtr
generates a significant amount of network traffic. Using
.B mtr
to measure the quality of your network may result in decreased
network performance.

.TP
.B \-w
.TP
.B \-\-report-wide

Clearly what happened here is someone intended to type \-c but
left out the '-'. Then troff cheerfully interpreted the \c and
the resulting omission in the formatted output is difficult to spot.
