7e2dfdd726 General: 
o Added global static chars mainPrompt and continuePrompt.
o Moved Argv0 declaration to head of file. Needed in do_meta_command,
  previously found below that.
o Added struct previous_mode_data to support new .explain toggle
  functionality.
o Added nullvalue, explainPrev and outfile members to
  struct callback_data.
o Added modeDescr array for number/text translation ofdisplay modes.
o Modified zHelp to match new functionality.

callback():
o Added support for .nullvalue

do_meta_command():
o Output filename is now saved to callback struct. If using stdout,
  then the string "stdout" is saved.
o Explain is now a toggle. When it is turned on, the current values of
  mode, header and colWidth are saved if not already in explain mode.
  When turned off, those values are restored.
o Allow .mode plurals columns and lines and dot command plural
  .headers.
o Added processing for new keywords .quit, .nullvalue, .show, .prompt.

main():
o Added -init as an option to override .sqliterc.
o Added -nullvalue as a command line option.
o Processes .sqliterc.

main_init():
o Genesis. Moved some initialization code here from inside main() so
  that it can be called initially by main and again if -init is
  specified.

one_input_line():
o Now takes prompts from settable values.

process_sqliterc():
o Genesis. Read .sqliterc from user's home directory and pass it to
  process_input(). File should contain meta commands for setups. (CVS 531)
