keyword: suppress keyword expansion while 'hg unshelve' for internal merge Before this patch, 'hg unshelve' may cause unexpected conflict, if 'hg unshelve'-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 unshelve' for internal merge by adding 'unshelve' to 'restricted' command list like 'merge'.
