revlog: document that mmap resources are released implicitly by GC
It's okay-ish, but currently the open fd and the mapping itself are leaked
until the indexdata is deallocated. If revlog had close(), the underlying
resources should be closed there as well, but AFAIK there's no such hook
point.
Revert interactive tests
1 add and commit file f
2 add commit file folder1/g
3 add and commit file folder2/h
4 add and commit file folder1/i
5 commit change to file f
6 commit changes to files folder1/g folder2/h
7 commit changes to files folder1/g folder2/h
8 revert interactive to commit id 2 (line 3 above), check that folder1/i is removed and
9 make workdir match 7
10 run the same test than 8 from within folder1 and check same expectations

Check editing files newly added by a revert
1) Create a dummy editor changing 1 to 42
$ cat > $TESTTMP/editor.sh << '__EOF__'
> cat "$1" | sed "s/1/42/g" > tt
> mv tt "$1"
> __EOF__
2) Add k
$ printf "1\n" > k
$ hg add k
$ hg commit -m "add k"
3) Use interactive revert with editing (replacing +1 with +42):
$ printf "0\n2\n" > k
$ HGEDITOR="\"sh\" \"${TESTTMP}/editor.sh\"" hg revert -i <<EOF
> y
> e
