[PATCH v3 00/11] gc docs: modernize the advice for manually running "gc"

Patch v3 fixes a minor grammar issue noted by Junio in <xmqqtvfvphv6.fsf@gitster-ct.c.googlers.com>, and another "while I'm at it" formatting error.

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
