cmdutil: put recordfunc invocation into wlock scope for consistency

Before this patch, 'recordfunc()' for interactive hunk selection does
below outside wlock scope at 'hg commit -i' and so on:

  - backup files, which may be partially changed
  - apply selected hunks on files
  - restore files from backup-ed ones

These should be executed inside wlock scope for consistency.

To put them into wlock scope without largely changing indents in
'recordfunc()', this patch adds another wrapper function.

This patch is also a preparation for subsequent patch fixing the issue
to correctly recognize partially committed files as "modified".

  $ hg init
  $ echo a > a
  $ hg ci -Ama
  adding a

  $ echo b > b
  $ hg branch b
  marked working directory as branch b
  (branches are permanent and global, did you want a bookmark?)
  $ hg ci -Amb
  adding b

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

Fast-forward:

  $ hg merge b
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci -Ammerge

Bogus fast-forward should fail:

  $ hg merge b
  abort: merging with a working directory ancestor has no effect
  [255]

Even with strange revset (issue4465)

  $ hg merge ::.
  abort: merging with a working directory ancestor has no effect
