check-code: fix issues with finding patterns in unified tests, fix tests

- old-style patterns without ^ were getting improperly anchored
- finditer was matching against beginning of line poorly
- \s was matching newlines
- [^x] was matching newlines

so we:

- remove earlier hacks for multiline matching
- fix unified test anchoring by adding .*
- replace \s with [ \t]
- replace [^x] with [^\nx]
- force all matches into multiline mode so ^ anchors work

This uncovers a number of test issues that are then repaired.

  $ hg init

  $ echo 123 > a
  $ hg add a
  $ hg commit -m "first" a

  $ mkdir sub
  $ echo 321 > sub/b
  $ hg add sub/b
  $ hg commit -m "second" sub/b

  $ cat sub/b
  321

  $ hg co 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

  $ cat sub/b 2>/dev/null || echo "sub/b not present"
  sub/b not present

  $ test -d sub || echo "sub not present"
  sub not present
