 1    0000              ; end of line can be now escaped with backslash (to concatenate multiple lines into one)
 2    0000              ; but the implementation is fairly limited:
 3    0000              ; - the total line length is still 2k chars max
 4    0000              ; - line numbers reported for errors are pointing to last line of full line
 5    0000              ; - listing file shows only concatenated line with last line number
 6    0000              ; - eol-comments can't be split (they end with EOL even when backslash is there)
 7    0000              ; - not even trying what will happen to SLD spans when colons and \ are intermixed
