Combining escape sequences

Escape sequences may be written in separate strings (figure 3-3)
or linked together for simplicity (figure 3-4). Commands with
variables may be combined if the variable sequence character and
the group character are the same for each command. The
following rules apply:

The escape character, the variable sequence character, and
the group character are omitted from all but the first escape
sequence when sequences are combined.
