======What is a word?======
The client supports several kinds of words:

^ Name ^ Description ^
| uword | "Unquoted word" does not support double quotes; cannot contain a space. |
| qword | "Quoted word" supports double quotes, and they are considered part of the word. Can contain any character. |
| dword | "Double quoted word" is a qword that has been "dequoted" or had its double quoted removed. |
| word | Either a uword, or a dword, depending on /xdebug dword |
| eword | Either a uword, or a dword, depending on /xdebug extractw |

======No really, what is a "word"?=====
A "word" is a uword if [[xdebug]] dword is turned off, and it is a dword
if [[xdebug]] dword is turned on.

======What is an "xword"?======
An "eword" is a uword if [[xdebug]] extractw is turned off, and it is a dword
if [[xdebug]] extractw is turned on.

======Why does it matter?======
Built in functions take a string as an argument.
Many of these functions must interpret this string as a
list of words.  Usually, all arguments are words (which means they do not
support double quoted words if [[xdebug]] dword is off), unless the help file
says that the argument is a dword.

The situation with built in commands is not quite as clear (yet).  This is
going to be addressed going forward.
