brnt --set-editor EDITOR-PATHNAME

• save editor to a config file
• flag to include/omit extension in the text file
• dry-run
• handle situation where files must be renamed in certain order or with temporary filenames to avoid files clashing mid-process
• detect invalid situations:
  • 0 files matched pattern
  • files which have unworkable filenames to start with e.g. newlines in filename
  • new filenames provided contain illegal characters e.g. asterisk, question mark
  • new filenames provided contain duplicates
  • new filenames provided clash with other files in the target location
  • making sure that the definition of "duplicate" and "clash" varies with filesystem case sensitivity?
• the ability to invoke text editor with custom arguments (beyond just the buffer filename)
• handle file-cannot-be-modified gracefully with choice to retry / abort / rollback / skip
• display output in way that divides into renamed | unchanged by choice | failed
• undo
