Splitting of multiple authors

[Jellby]

While reviewing the translated strings I found this one:

By default, calibre splits a string containing multiple author names on
ampersands and the words "and" and "with". You can customize the splitting
by changing the regular expression below. Strings are split on whatever the
specified regular expression matches.
Default: r'(?i),?\s+(and|with)\s+'

Maybe I'm wrong, but it seems to me that the description doesn't match the default value, which matches only and/with, with an optional comma. Which is correct?

Splitting on ampersands happens always irrespective of the regex, the regex is really used to specify additional things to split on, I've updated the documentation to make that clearer.
