+======Synopsis:======
+$[[joinstr]](//seperator// //var1// //var2//)
+======Description:======
+This function joins two word lists together with a seperator. Formally:
+This function returns a word list wherein the **N**th word of the return
+value is the string catenation of the **N**th word of $//var1//, the
+//seperator//, and the **N**th word of $//var2//.  Please note that //var1//
+and //var2// must be variable names, not the values themselves.
+You can join together more than two variables in this way: just list the
+variable names.
+If one variable has less words than another variable, then the empty value
+is used to hold the place of any missing words.
+======Practical:======
+If you had two variables, one containing nicks and the other containing
+user@hosts, you might use a function like [[copattern]] to turn user@host
+wildcards into nicknames.  But if you wanted to create nick!user@hosts,
+you could use this function:
+	@nicks = [one two three]
+	@userhosts = [foo@baz.com boo@ya.com bar@oof.com]
+	@nuh = joinstr(! nicks userhosts)
+	echo $nuh
+would output
+	one!foo@baz.com two!boo@ya.com three!bar@oof.com
+======History:======
+The [[joinstr]] function first appeared in EPIC4-1.1.8.
+The ability to join more than two variables first appeared in EPIC4-1.1.15.
