This example in the Texinfo manual doesn't produce the claimed output.

@Example
A caf
\o
e\'


in Paris
  @result{} A café in Paris
@endExample

First, there are three newline characters (one ending the line, and two more
forming blank lines) following the overstruck "e\'" sequence; the first of
these closes the \o escape, as the example is intended to illustrate, but the
other two cause a break, which puts the result not all on one line as shown.

Second, the newline between "caf" and "\o" outputs (in fill mode) a space,
resulting not in "café" but in "caf é".

Example input that produces the claimed output would be:

@Example
A caf\o
e\'
in Paris

This is also visually tighter while still illustrating the ability of newlines
to delimit \o's argument.
