rust: fix non-utf8 char in requirements.rs

Apparently Phabricator detect `rust/hg-core/src/requirements.rs` file as non
utf8 ‽, and mark it as binary.  During application it ended up being non-utf8
and this made Rust (and as a result heptapod) very angry::

    error: couldn't read hg-core/src/requirements.rs: stream did not contain valid UTF-8
      --> hg-core/src/lib.rs:11:9
       |
    11 | pub mod requirements;
       |         ^^^^^^^^^^^^

    error: aborting due to previous error

    error: could not compile `hg-core`.

The after "fixing", the file content has no character matching the following
regexp:

  [^0-9-a-zA-Z /(|).,{}!\[\]:"&=>?_*-;<`'#]

So we should be fine, unless Phabricator does something funny again.

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)
