# $EPIC: match,v 1.7 2002/01/13 00:27:11 anders Exp $
Synopsis:
   $match(<pattern> <word list>)

Technical:
   * If the <pattern> argument is omitted the empty string is returned.
   * <word list> contains zero or more space separated "extended words"
   * Each word in <word list> is taken as literal text, and each are matched
     against <pattern>.
   * If none of the words in <word list> are matched by <pattern>, then the 
     return value of match is 0 (zero).
   * Otherwise, the return value is the index of the first word in <word list>
     that is matched by <pattern>, COUNTING FROM ONE, AND NOT COUNTING FROM 
     ZERO.
   * It is important to remember that other word functions, such as word
     count from zero.  You must subtract one from the return value of this 
     function before you can use it in some other functions.
   * If <pattern> does not contain any wildcards, you should use the 
     $findw() function instead.
   * If <word list> contains only one word, you should use the =~ operator
     instead.

Practical:
   This function can be used to match a pattern against a list of words
   to see if any of them match.  Since ircII does not include the =~ operator,
   this was the standard way to do pattern matching of one pattern to one
   string in scripts.  Also, since ircII does not include the findw
   function, this was the standard way to determine if a literal word was
   present in a literal word list.  In many cases, the match function 
   has been superseded by other functions that do the job better.

Returns:
    0   no matches found
   >0   index to first match in list -- counting from one!

Examples:
   $match(*oo* blah foo booya)                              returns 2
   $match(*oo* blah fubar erf)                              returns 0

History:
   This function first appeared in ircII-2.1.5
