title: How do you print to a text file in GAP without linebreaks?
body: <p>Minimum working example:</p>
  
  <pre class="lang-gap prettyprint-override"><code>x:=Indeterminate(Rationals,&quot;x&quot;);
  f:=Sum([1..1000],i-&gt;x^i);
  PrintTo(&quot;~/temp.txt&quot;,f);
  </code></pre>
  <p>It prints to <code>temp.txt</code> the following:</p>
  <pre class="lang-gap prettyprint-override"><code>x^1000+x^999+x^998+x^997+x^996+x^995+x^994+x^993+x^992+x^991+x^990+x^989+x^988\
  +x^987+x^986+x^985+x^984+x^983+x^982+x^981+x^980+x^979+x^978+x^977+x^976+x^975\
  +x^974+x^973+x^972+x^971+x^970+x^969+x^968+x^967+x^966+x^965+x^964+x^963+x^962\
  +x^961+x^960+x^959+x^958+x^957+x^956+x^955+x^954+x^953+x^952+x^951+x^950+x^949\

  <p>How can I instead get it to print it on a single line in the text file?</p>
