-Return the first quoted string and the remainder of the string.
+Return the first quoted string and the remainder of the string, as separated by

+whitespace. The C<$q> is not unquoted.

+Split string on unquoted whitespace. Multiple consecutive spaces are I<not>

+=item C<split_quoted_strings_friendly($str)>
+
+Similar to C<split_quoted_strings>, but intended for user-friendly uses. In
+particular, this function treats any sequence of zero or more whitespace
+characters as a separator, rather than the more strict interpretation applied
+by C<split_quoted_strings>. All of the strings are unquoted.
All of these quoting-related functions are available under the export
tag C<:quoting>.
