Maybe you got me wrong. Consider the attached texi file, which makeinfo
converts to the attached HTML file.

If you apply the following CSS to the HTML file

<style type="text/css">
pre.smallexample {
  border: 1px solid red;
  padding: 0;
}
</style>

you see what I mean. Even though the container gets a padding of 0, the
text still does not start on the very left of the container. This is
because the preformatted text is rendered as

<pre class="smallexample">     This is
         a small
     example
</pre>

where

<pre class="smallexample">This is
    a small
example
</pre>

would be correct, since I have no way of removing the additional
whitespace with CSS foo. The problem gets uglier, if @example and
@smallexample are used deeper down the document tree, because additional
"prefix" whitespaces are then added.

However, I've looked into the manual of @exampleindent and this does
what I want, obviously [0] states

        "@exampleindent is ignored for HTML output."

which apparently is no longer true for at least version 4.13. So putting

@ifhtml
@exampleindent 0
@end ifhtml

in the header fixes my problem.

Thanks for your help!
Thomas.
