[PATCH v4 00/11] gc docs: modernize and fix the documentation

v4 fixes a misbalanced quote noted by Todd Zullinger in <20190330180415.GC4047@pobox.com>, and makes this equivalent to the post-squash version sitting in gitster/ab/gc-docs now.

Ævar Arnfjörð Bjarmason (11):
  gc docs: modernize the advice for manually running "gc"
  gc docs: stop noting "repack" flags
  gc docs: clean grammar for "gc.bigPackThreshold"
  gc docs: include the "gc.*" section from "config" in "gc"
  gc docs: re-flow the "gc.*" section in "config"
  gc docs: fix formatting for "gc.writeCommitGraph"
  gc docs: note how --aggressive impacts --window & --depth
  gc docs: downplay the usefulness of --aggressive
  gc docs: note "gc --aggressive" in "fast-import"
  gc docs: clarify that "gc" doesn't throw away referenced objects
  gc docs: remove incorrect reference to gc.auto=0
