formatter: add helper to create a formatter optionally backed by file
To make things simple, openformatter() and maybereopen() have no support
for a plain object API. Callers must use the "with" statement.
Unlike cmdutil.makefileobj(), append mode ('ab') isn't supported by these
functions. This is because JSON output can't be simply concatenated. Perhaps
cmdutil.export() will have to build a {filename: [revs...]} map first and
write revs per file.
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
