tests: add a test demonstrate that 'revert -i' ignores nonexistent patterns

As described in issue5789, when revert is called through:

  hg revert -i <some file that does not exist>

we'd expect the command to abort early. Currently, it just warns about
missing file but prompt about files unrelated to user arguments.

 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
