help/config: note 64-bit Windows registry key used with 32-bit Python Before this patch the only place that documented the use of a different registry key was on the wiki page for installing on Windows from sources, while most users will use a pre-packaged installer and the supplied help files. This patch documents in the supplied help files that an alternate registry key is used for the installation/system configuration file when using 32-bit Python on a 64-bit Windows.

splicemap: support paths with spaces in splicemap (issue3844) Shlex module was used to split line as suggested. Split operates in POSIX mode.

branch: strip whitespace before testing known branch name Because dirstate._branch() strips leading/trailing spaces from .hg/branch, "hg branch ' foo '" should abort if branch "foo" exists in another head. tag command had a similar bug and fixed by 3d0a9c8d7184.

copies: refactor checkcopies() into a top level method This moves checkcopies() out of mergecopies() and makes it a top level function in the copies module. This allows extensions to override it. For example, I'm developing a filelog replacement that doesn't have rev numbers so all the rev number dependent implementation here needs to be replaced by the extension. No logic is changed in this commit.

store: move top file walk to a separate function Some extensions find it useful to be able to walk the non-data files in the repo, so I'm moving that part of the walk to a separate function. In particular, this allows an extension to interact with only the non-filelog store data (for instance, when cloning everything but filelogs).
