class String
# Returns a new string with all new lines removed from
# adjacent lines of text.

# s = "This is\na test.\n\nIt clumps\nlines of text."
# s.fold

# _produces_

# "This is a test.\n\nIt clumps lines of text. "
#
# One arguable flaw with this, that might need a fix:
# if the given string ends in a newline, it is replaced with
# a single space.
