How universal is the convention of no space after unary operators?
Depends on the operator of course ;-). Operators like "not" and "abs"
will be followed by a space usually, but a space after a unary "+" or "-"
would be very confusing (at least to me). Code like
A := + 3;
makes me think an A was forgotten after the ":=".
I'd think for error recovery purposes it is safe to assume that
unary plus/minus is not followed by a space. So plus/minus followed
by space is binary and "missing operand" is correct diagnosis,
otherwise operator may be unary or binary and the longer message
should be given.
