evolve: precursors, successors and troubles are just aliases now

These template keywords follow the old vocabulary, and shouldn't be used, but
we provide them for the time being anyway.

Also mentioning them here will hopefully some day make `hg help -k` find them.

# This script finds compatibility-related comments with a node hash specified
# in all files in a given directory (. by default) and looks up the hash in a
# repo (~/hg by default) to determine if each of the comments is correct and,
# if not, it suggests the correct release. This can prevent accidentally
# removing a piece of code that was misattributed to a different (earlier)
# release of core hg.

# Usage: $0 WDIR HGREPO where WDIR is usually evolve/hgext3rd/ and HGREPO is
# the place with core Mercurial repo (not just checkout). Said repo has to be
# sufficiently up-to-date, otherwise this script may not work correctly.
