 * Defining EXPAND_TO will print the list of expanded addresses on an added
 * X-PH-To: header line.  This will also expand names found in /usr/lib/aliases
 * lists.  Leaving it undefined will cause phquery to print only a version
 * line with the name of the host running phquery, e.g.,
 * X-Ph: V3.5@uxc.cso.uiuc.edu .

/*
 * An address tested as a name is first run through as is.  If no matches
 * are found then any punctuation characters are converted one at a time
 * (leftmost first) to space characters and the lookup is repeated until
 * there are no more punctuation characters.  If WILDNAMES is #define'd,
 * a wildcard char '*' will be appended after each single character name,
 * e.g. p-pomes is tried as "p* pomes".  This has risks as follows:  assume
 * Duncan Lawrie sets his alias to "lawrie".  A query for d-lawrie will
 * fail as a alias lookup but succeed as a name lookup when written as
 * "d* lawrie".  This works until Joe Student sets his alias to "d-lawrie".
 * Whoops.  Still in a non-hostile environment, this function may be more
 * useful than dangerous.
