the input. Unless the run of spaces in the format string
appears adjacent to a newline, the run must consume at least
one space from the input or find the end of the input.

The handling of spaces and newlines differs from that of C's
scanf family: in C, newlines are treated as any other space,
and it is never an error when a run of spaces in the format
string finds no spaces to consume in the input.

The patterns used by [ServeMux] now allow one or more spaces or tabs after the method name.
