2018-12-05bc: handle BIN_FILE and LEX_BAD_CHAR errors at the site of detectionDenys Vlasenko
The most informative message can be generated at the location where error is detected. The "error codes" are stupid: print error meesage immediately, then just return "there was an error" indicator. All error codes will be converted. For now, converting these two. For now, this and following changes will degrade error messages quality. For example, file name and line number printouts may be lost. This will be re-added later.

2018-12-03vi: correctly detect when a deletion empties the bufferRon Yorston
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.

2018-11-27hush: allow hush to run embedded scriptsRon Yorston
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.
