[manual] Specify what is the return value of strrep

[Francesco Potorti`]

No changelog for this trivial change.

I managed to put non-ascii7 characters in my name by setting the env var
HGENCODING=ISO-8859-15.

Now, does anyone know ho to pass additional parameters to the diff used
by 'hg export'?  I would like to pass -pb, but I cannot guess how.
