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.
