Recoded regexp:split and regexp:gsub calls to avoid regexp.
Tidied and corrected split functions:
o renamed slash_split/1,3 to split_content/1,3;
o removed strip_leading_blank (effect now in strip_content/1 matching);
o removed push_non_null_rstr/2;
o made both splits preserve order;
o splits now treat null string correctly.
Rewrite split_* to split/2; taking Splitter list as parm.
