" Options returns callbacks to be used with job_start. It is abstracted to be
" used with various go commands, such as build, test, install, etc.. This
" allows us to avoid writing the same callback over and over for some
" commands. It's fully customizable so each command can change it to its own
" logic.
"
" args is a dictionary with the these keys:
" 'bang':
" Set to 0 to jump to the first error in the error list.
" Defaults to 0.
" 'statustype':
" The status type to use when updating the status.
" See statusline.vim.
" 'for':
" The g:go_list_type_command key to use to get the error list type to use.
" Errors will not be handled when the value is '_'.
" Defaults to '_job'
" 'errorformat':
" The errorformat string to use when parsing errors. Defaults to
" &errorformat.
" See :help 'errorformat'.
" 'complete':
" A function to call after the job exits and the channel is closed. The
" function will be passed three arguments: the job, its exit code, and the
" list of messages received from the channel. The default is a no-op. A
" custom value can modify the messages before they are processed by the
" returned exit_cb and close_cb callbacks.
" The return value is a dictionary with these keys:
" 'callback':
" A function suitable to be passed as a job callback handler. See
" job-callback.
" 'exit_cb':
" A function suitable to be passed as a job exit_cb handler. See
" job-exit_cb.
" 'close_cb':
" A function suitable to be passed as a job close_cb handler. See
" job-close_cb.
" 'cwd':
" The path to the directory which contains the current buffer. The
" callbacks are configured to expect this directory is the working
" directory for the job; it should not be modified by callers.
