histedit: use 'util.ellipsis' to trim description of each changesets

Before this patch, trimming description of each changesets in histedit
may split at intermediate multi-byte sequence.

This patch uses 'util.ellipsis' to trim description of each changesets
instead of directly slicing byte sequence.

Even though 'util.ellipsis' adds '...' as ellipsis when specified
string is trimmed (= this changes result of trimming), this patch uses
it, because:

  - it can be used without any additional 'import', and
  - ellipsis seems to be better than just trimming, for usability
