keyword: restore kwtemplater.restrict at the end of wrapped patch.diff

Before this patch, kwdiff doesn't restore kwtemplater.restrict after
invocation of wrapped patch.diff(). This suppresses keyword expansion
at subsequent filelog.read().

Typical usecase of this issue is "hg cat" after "hg diff" with command
server. In this case, kwtemplater.restrict=True is kept in command
server process even after "hg diff".

To ensure kwtemplater.restrict=True while original patch.diff()
running, this patch makes kwdiff() yield values returned by it,
because it returns generator object.

Strictly speaking, if filelog.read() is invoked before completely
evaluating the result of previous patch.diff(), keyword expansion is
still suppressed, because kwtemplater.restrict isn't restored yet.

But this fixing should be reasonable enough, because patch.diff() is
consumed immediately, AFAIK.

Test that patch.diff(), which is implied by "hg diff" or so, doesn't
suppress expanding keywords at subsequent commands
