improve semantic history pattern to detect line numbers and columns

Currently iterm is able to open the files but is not able to pass the line number to the command executed.

expected <block end>, but found %r" % token.id, token.start_mark)
yaml.parser.ParserError: while parsing a block collection
in "/Users/john/jobs.yaml", line 132, column 14
expected <block end>, but found '<block mapping start>'
in "/Users/john/jobs.yaml", line 135, column 20

Apparently there is support for line numbers but only when the output format looks like path:line. Column support is totally missing.
