title: Need explanation of tcl regexp inline example in the man page please
body: <p>While trying to understand  regexp and --inline use, saw this example but couldn't understand how it works.</p>
  
  <p>Link to the man page is: <a href="http://www.tcl.tk/man/tcl8.4/TclCmd/regexp.htm#M13" rel="nofollow">http://www.tcl.tk/man/tcl8.4/TclCmd/regexp.htm#M13</a>
  In there, under --inline option, this example was given:</p>
  
  <pre><code> regexp -inline -- {\w(\w)} " inlined "
   =&gt; {in n}
  regexp -all -inline -- {\w(\w)} " inlined "
   =&gt; {in n li i ne e}
  </code></pre>
  
  <p>How does this "{\w(\w)}" yield "{in n}"?  Can someone explain please.
  Appreciate the help.</p>
  
  <p>Thanks</p>
