bookmarks: prevent divergent bookmark from being updated unexpectedly

Before this patch, "@99" suffixed bookmark may be updated unexpectedly
by the bookmark value on the remote side at "hg pull", if all of "@1"
to "@99" suffixed bookmarks exist in the local repository, because
variable "n" still refers "@99" suffixed bookmark after the loop to
examine "@num" suffixes, even though it already exists in the local
repository.

This patch prevents divergent bookmark from being updated
unexpectedly, and shows warning message in such situation.

This patch uses original python script "seq.py" instead of "seq"
command to create sequence numbers in the test, because "seq" command
may not be available: it isn't defined in recent POSIX specification
(POSIX.1-2001 2013 Edition or XPG7)
