-- The main purpose of the bletcherous parse() is to split a line into words and and then for each eligible word

-- The simple job of splitting at whitespaces has been made complicated by a) the fact that the input can contain
-- whitespaces inside the various html elements that are the result of the application of various formatting templates;
-- and b) the need to be able to recognise the output of the template that formats custom gloss abbreviations
-- (and hence skip passing it on to find_gloss). See talk for a suggestion about its future.
