subrepo: make "_sanitize()" work

"_sanitize()" was introduced by 224e96078708 on "stable" branch, but
it has done nothing for sanitizing since 224e96078708.

"_sanitize()" assumes "Visitor" design pattern:

    "os.walk()" should invoke specified function ("v" in this case)
    for each directory elements under specified path

but "os.walk()" assumes "Iterator" design pattern:

    callers of it should drive loop to scan each directory elements
    under specified path by themselves with the returned generator
    object

Because of this mismatching, "_sanitize()" just discards the generator
object returned by "os.walk()" and does nothing for sanitizing.

This patch makes "_sanitize()" work.

This patch also changes the format of warning message to show each
unlinked files, for multiple appearances of "potentially hostile
.hg/hgrc".

  $ hg init
  $ touch unknown

  $ touch a
  $ hg add a
  $ hg ci -m "1"

  $ touch b
  $ hg add b
  $ hg ci -m "2"

Should show unknown

  $ hg status
  ? unknown
  $ hg revert -r 0 --all
  removing b

Should show unknown and b removed

  $ hg status
  R b
  ? unknown

Should show a and unknown

  $ ls
  a
  unknown
