Write fifo

Purpose: Write key/value pair into a FIFO list.

 write-fifo <list> \
     key <key> \
     value <value>

write-fifo adds a pair of key/value pointers to the FIFO <list>, specified with strings <key> and <value> (in "key" and "value" clauses, collectively called an "element").

It always adds elements to the end of the list.

Examples

 new-fifo nf
 write-fifo nf key "mykey" value "myvalue"
