evolve: use util.unlinkpath() via vfs

Internally vfs.unlinkpath() does the path join and calls util.unlinkpath(). So
the new form is equivalent, just shorter.

This method exists in 4.8, so the new code shouldn't have any compatibility
issues.

#!/bin/bash
set -euox pipefail

unset GREP_OPTIONS

compatbranches=$(hg branches --quiet | grep 'mercurial-' | grep -v ':' | sort -n --reverse)
prev='stable'
topic=${1:-'test-compat'}
for branch in $compatbranches; do
    # Logic in the revsets below:
    # 1. There is target topic on stable or compatibility branch: merge all
    # those commits, they are related to our work and need to pass tests on all
    # compatibility branches.
    # 2. There is no target topic: avoid any commits that have topic set, they
    # are definitely unrelated to what we're doing.
    # In other words, if you want to test certain commits, assign them all to
    # one topic and provide that topic as the first argument to this script.
    uptarget="first(max(branch('$branch') and topic('$topic')) or max(branch('$branch') and not topic()))"
    hg up -r "$uptarget"
    hg topic "$topic"
    mergetarget="first(max(branch('$prev') and topic('$topic')) or max(branch('$prev') and not topic()))"
    hg merge -r "$mergetarget"
    hg commit -m "test-compat: merge $prev into $branch"
    prev=$branch
done
