sh: Fix crash with empty functions (f() { }) introduced in r196483 Empty pairs of braces are represented by a NULL node pointer, just like empty lines at the top level. Support for empty pairs of braces may be removed later. They make the code more complex, have inconsistent behaviour (may or may not change $?), are not specified by POSIX and are not allowed by some other shells like bash, dash and ksh93.

sh: Get rid of unnecessary non-standard empty lists. POSIX does not allow constructs like: if cmd; then fi { } Add a colon dummy command, except in a test that verifies that such empty lists do not cause crashes when used as a function definition. 2010-08-16 13:18:08 -04:00			`# The empty pairs of braces here are to test that this does not cause a crash.`
