Building upon our work in the previous commit to add members 'columnnum'
and 'color_columno' to 'grep_opt', we teach show_line() how to respect
those options.
When requested, show_line() will display the column number of the first
match on a non-context line. show_line() differentiates between context
and non-context lines through the '&& cno' check. 'cno' will be equal to
zero if and only if show_line() is invoked on a context line. It will be
a non-zero value otherwise.
