[PATCH 2/2] parse-options: remove the unused parse_opt_commits() function

[Ramsay Jones]

Commit fcfba37337 ('ref-filter: make "--contains <id>" less chatty if
<id> is invalid', 2018-02-23), removed the last use of the callback
function parse_opt_commits(). Remove this function declaration and
definition, since it is now dead code.
