- * Insert output of command.
- * %(test_text=pattern?if_text:else_text)
- * Substitute if_text if test_text matches pattern, otherwise

- * Put ^ in the middle to capitalize the first letter: %^C = Net.jokes
- * Put _ in the middle to capitalize last component: %_c = net/Jokes
- *
- * ~ interpretation in filename expansion happens after % expansion, so
- * you could put ~%{NEWSLOGNAME-news} and it will expand correctly.
