keyword: suppress keyword expansion while 'hg rebase' for internal merge

Before this patch, 'hg rebase' may cause unexpected conflict, if 'hg
rebase'-ed changes are located near lines in which keywords are
embedded, because keywords are substituted with other strings in the
working directory.

This patch suppresses keyword expansion while 'hg rebase' for internal
merge by adding 'rebase' to 'restricted' command list like 'merge'.

This patch specifies '--keep' to 'hg rebase', because revision #10 is
useful also for tests in succeeding patches.
