^Cready for more input

interrupt (type "quit" to exit)

d08206dce1 vi: correctly detect when a deletion empties the buffer
Michał Berger has reported two issues:

- Repeatedly deleting and undoing the deletion of the last line
  results in characters being lost from the end of the line.

- Deleting the bottom line twice then attempting to undo each of
  these deletions results in a segfault.

The problem seems to be an incorrect test for whether the text buffer
is empty.

71df2d3589 hush: allow hush to run embedded scripts
Embedded scripts require a shell to be present in the BusyBox
binary.  Allow either ash or hush to be used for this purpose.
If both are enabled ash takes precedence.

The size of the binary is unchanged in the default configuration:
both ash and hush are present but support for embedded scripts
isn't compiled into hush.

2d217799e8 build system: prevent duplicate applet names
The embedded script feature makes it easier to create applets with
duplicate names.  Currently in such cases the build succeeds but
the resulting executable doesn't work as the developer intended.

Catch duplicate names when the applet tables are being generated
and make the build fail.

7b42f8fc76 Tweaks to build process for embedded scripts
- Force a rebuild if a script in applets_sh is changed.

- Move the dummy usage messages for custom applets to usage.h and
  change the name from 'dummy' to 'scripted'.

- Hide an error from gen_build_files.sh if an embed directory exists
  but is empty.

- Tidy up embedded_scripts script.

v2: Remove a couple of unnecessary tests in embedded_scripts, as
    pointed out by Xabier Oneca.
    Drop the stripping of comments.
