histedit: correct the number of added revisions in online help

In the context of help document on which this patch focuses, the
example repository, which is source of cloning, should be already
histedit-ed, and contain only 3 revisions (rev # 0 to 2). So, not 3,
but 4 revisions should be added to the destination repository of
cloning, if it contains 7 revisions (rev # 0 to 6).

This patch also adds modifier "histedit-ed" to "example repository",
to make context clear.

Make sure update doesn't assume b1 is a repository if invoked from outside:

  $ cd ..
  $ hg update b1
  abort: no repository found in '$TESTTMP' (.hg not found)!
  [255]
  $ cd b1

Test helper functions:

  $ revtest () {

Test cases are documented in a table in the update function of merge.py.
Cases are run as shown in that table, row by row.
