title: Print whole string verbatim in gdb
body: <p>I'm printing a string(char *) in gdb</p>
  
  <pre><code>(gdb) p l
  l=0x9aa1f48 "up2 129104596496602200 19 0 0 3 0 eth1 XX :001CB",'0' &lt;repeats 12 times&gt;, "DC"
  </code></pre>
  
  <p>Is there a setting to have <code>p</code> print the whole string and not fill inn the "repeats ... ". While at it - also extend the default printable length of a string, <code>p</code> seems to cut off if the string is quite long.</p>
