Thanks for the suggestion, but this already does what you want:

calc `wc -m < file`/`wc -l < file`

That is, POSIX requires that when reading from stdin rather than from a
filename, then there will be no filename in the output of wc.  As this
is already a standard way to suppress the output, I see no need to add a -q.
