Hi,
thank you both for the detailed explanation. I had fully forgotten about the binary meaning of -a. However, it makes me wonder why this isn't more visibly documented.
The current devel branch man page says this:
The historical operator-precedence parsing with 4 or more argu-
ments can lead to ambiguities when it encounters strings that
look like primaries. The POSIX standard has deprecated the -a
and -o primaries and enclosing expressions within parentheses.
Scripts should no longer use them. It's much more reliable to
restrict test invocations to a single primary, and to replace
uses of -a and -o with the shell's && and || list operators.
