In sh, is '[' a portable synonym for 'test'?

[Ed Reeder]

Another reason '[' is used instead of test is it prevents problems
when the user has a file named 'test' in his current directory AND
his search path searches his current directory before /bin (for
systems that don't have test built in to the shell).

While everyone should reset PATH to avoid the problem, we don't
(as evidenced by net.sources).
