- Trim rhetorics from description and compact it.

- Update to version 3.1
* Added the --raise-dtr and --raise-rts options, for symmetry with
--lower-dtr and --lower-rts (see manual page for details)
* Better build support for custom baudrates. Now custom baudrate
support is enabled by default for some systems
* You can always explicitly enable custom baudrate support for
other systems and you can explicitly disable it, even for the
systems it is automatically enabled for (see Makefile).
* To see if custom baudrate support is enabled in your build, run
picocom with the --help command-line option.
- Includes 3.0
* Added the --logfile command line option
* Added the --lower-rts and --lower-dtr command-line options.
These options lower (reset) the respective modem control lines
of the serial port, as soon as picocom starts and the port
is configured.
* Added the --initstring (or -t) command line option. This option
can be used to send an initialization string to the serial port
when picocom starts.
* Added the --exit-after (or -x) command line option. Causes
picocom to exit if it becomes idle for the specified time.
* Added the -exit (or -X) command line option. Causes picocom to
exit immediately after opening and configuring the serial port.
* Added the --quiet (or -q) command line option. Suppress output
from picocom that was not explicitly requested by the user.
Errors and command responses are still printed.
* Added the --no-escape (or -n) command line option. Disables the
escape character. If given picocom will never enter command mode.
