Merge branch 'ps/config-get-color-fixes'

The use of "git config get" command to learn how ANSI color
sequence is for a particular type, e.g., "git config get
--type=color --default=reset no.such.thing", isn't very ergonomic.

* ps/config-get-color-fixes:
  builtin/config: do not spawn pager when printing color codes
  builtin/config: special-case retrieving colors without a key
  builtin/config: do not die in `get_color()`
  t1300: small style fixups
  t1300: write test expectations in the test's body
