urlutil: add a `get_clone_path` function

We add a new function with a semantic focussed on `clone` operation (so without
an existing repository). I am not certain the return type is the best, but this
is what we need for now. Once all caller are migrated we might start thinking
about that the API should be. For now that will do.

Revert interactive tests with the Curses interface

  $ cat <<EOF >> $HGRCPATH
  > [ui]
  > interactive = true
  > interface = curses
  > [experimental]
  > crecordtest = testModeCommands
  > EOF

TODO: Make a curses version of the other tests from test-revert-interactive.t.

When a line without EOL is selected during "revert -i"

  $ hg init $TESTTMP/revert-i-curses-eol
  $ cd $TESTTMP/revert-i-curses-eol
  $ echo 0 > a
  $ hg ci -qAm 0
  $ printf 1 >> a
  $ hg ci -qAm 1
  $ cat a
  0
  1 (no-eol)

  $ cat <<EOF >testModeCommands
  > c
  > EOF

  $ hg revert -ir'.^'
  reverting a
  $ cat a
  0

When a selected line is reverted to have no EOL

  $ hg init $TESTTMP/revert-i-curses-eol2
  $ cd $TESTTMP/revert-i-curses-eol2
  $ printf 0 > a
  $ hg ci -qAm 0
  $ echo 0 > a
  $ hg ci -qAm 1
  $ cat a
  0

  $ cat <<EOF >testModeCommands
  > c
  > EOF

  $ hg revert -ir'.^'
  reverting a
  $ cat a
  0 (no-eol)
