[PATCH v2 0/2] config: list only variable names for completion

Fixed misspelled option names in docs and in commit message, incorporated Peff's suggestions, and renamed 'show_only_keys' to 'omit_values' in 1/2.

Only minor tweaking in 2/2's commit message.

SZEDER Gábor (2):
  config: add options to list only variable names
  completion: use new 'git config' options to reliably list variable
    names
