keyword: suppress keyword expansion while 'hg histedit' for internal merge
Before this patch, 'hg histedit' may cause unexpected conflict, if 'hg
histedit'-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 histedit' for
internal merge by adding 'histedit' to 'restricted' command list like
'merge'.
Test in this patch just swaps order of revision #13 and #14: this is
enough to cause internal merge.
