[PATCH 0 of 2 STABLE] keyword: preserve filemode, stricter testing of kwexpand/kwshrink, record

[Christian Ebert]

Hi,

Here are my recent patches for the keyword extension against
stable - not preserving filemode when overwriting to expand
keywords can be considered as a bug.

With stable the switch to the repo.wopener(..., atomictemp=True)
method fails and we have to resort to os.lstat; I guess that's
because in stable scmutil does not provide the filecache class,
but am happy to be corrected.
