Thanks.

I'd rephrase the last sentence like this:

  This is still the case by default, but if you customized
  'browse-url-mailto-function' to call some other function, it will
  now be called instead of the default.

Also, the "+++" means the change is documented in some manual, but no
changes for the manual are part of the patch, so I guess you meant
"---" instead.

Maybe we should point to the SHR entry instead of repeating almost the
same text.
