Merge branch 'mm/status-without-comment-char'

"git status" now omits the prefix to make its output a comment in a
commit log editor, which is not necessary for human consumption.

We may want to tighten the output to omit unnecessary trailing blank
lines, but that does not have to be in the scope of this series.

* mm/status-without-comment-char:
  t7508: avoid non-portable sed expression
  status: add missing blank line after list of "other" files
  tests: don't set status.displayCommentPrefix file-wide
  status: disable display of '#' comment prefix by default
  submodule summary: ignore --for-status option
  wt-status: use argv_array API
  builtin/stripspace.c: fix broken indentation
