update: use higher level wording for "crosses branches" error

When using "hg update" to update to a revision on another branch, if
the user has uncommitted changes in the working directory, hg aborts
with the following message:

  abort: crosses branches (use 'hg merge' to merge or use 'hg update
  -C' to discard changes)

If the user isn't trying to update to tip and they follow the command
examples verbatim, they would end up updating to the wrong revision.

This patch removes the command examples in favor of just telling the
user to either merge or use --clean:

  abort: crosses branches (merge branches or use --clean to discard
  changes)

hg also aborts if the user tries to use "hg update" to get to tip
(without specifying a revision) and tip is on another branch:

  abort: crosses branches (use 'hg merge' or use 'hg update -c')

This message is changed in the same fashion:

  abort: crosses branches (merge branches or use --check to force
  update)
