 Priority:  low           |   Milestone:  2.2      
Component:  General       |     Version:  2.1.3    
 Severity:  trivial       |    Keywords:  has-patch

 === Environment ===
 WordPress SVN {{{/branches/2.1}}} rev 5096

 Also affects {{{/trunk}}} (rev 5116) and WordPress MU {{{/tags/1.1.1}}}.

 === Details ===

 In {{{wp-includes/functions.php}}}, the {{{do_robots()}}} function serves
 up the contents of a {{{robots.txt}}} file. If you try to view the file in
 a web browser, the line breaks will not show up properly. This is because
 the mime-type served is the default {{{text/html}}} which instructs the
 browser to parse the {{{robots.txt}}} file as HTML. This should not be the
 case.

 {{{text/plain}}} is a good mime-type to use, and behaves correctly.

 The attached patch will cause the function to serve {{{robots.txt}}} as
 {{{text/plain}}}.
