Add markup-list-command string-lines
Splits its string-argument at line-break (per default, other
splitting characters are settable), removes surrounding
white-space from the resulting strings and returns a markup-list,
more precisely a list of stencils, ready to be formated by other
markup-(list-)commands.
This offers to a very conveniant method for entering additional
stanzas for songs and chorals.
