  * properly support Unicode encodings and the character-based model
    * link against libncursesw if possible

    could write a Macro file for each modified file containing

  * Add special Q-Register for dot:
    Would simplify inserting dot with string building and saving/restoring
    dot on the QReg stack
  * automatic EOL detection of buffers; easy EOL setting
  * command to change the current working directory. This will
    influence tab-completion and relative file names.
+ * exclusive access to all opened files/buffers (locking):
+   SciTECO will never be able to notice when a file has been
+   changed externally. Also reversing a file write will overwrite
+   any changes another process could have done on the file.
+   Therefore open buffers should be locked using the flock(), fcntl()
+   or lockf() interfaces. On Windows we can even enforce mandatory locks.
 
 Optimizations:
  * refactor search commands (create proper base class)
