} I can't get the short form of `if' to work, described in the manual as:

} A short form of the alternate `if'.
}
} What am I doing wrong?
The documentation does explain this:
The short versions below only work if SUBLIST is of the form
`{ LIST }' or if the SHORT_LOOPS option is set. In this case,
the test part of the loop must also be suitably delimited, such
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
as by `[[ ... ]]' or `(( ... ))', else the end of the test will
not be recognized.
"In this case" does NOT mean "if the SHORT_LOOPS option is set." It
should probably say "in either of these cases ..."
If I (dimly) recall correctly, the documentation originally said:
The short versions below only work if SUBLIST is of the form
`{ LIST }'. In this case, ...
And then later the SHORT_LOOPS option was added and the "or if ..." was
stuck into the sentence without fixing the rest of it.
