[PATCH 0/4] Replace use of `test <expr> -o/a <expr>`

Hi,

this patch series replaces all uses of `test <expr> -o/a <expr>` that I
was able to find in our codebase. This is in accordance to our coding
guidelines:

 - We do not write our "test" command with "-a" and "-o" and use "&&"
   or "||" to concatenate multiple "test" commands instead, because
   the use of "-a/-o" is often error-prone.  E.g.

     test -n "$x" -a "$a" = "$b"

   is buggy and breaks when $x is "=", but

     test -n "$x" && test "$a" = "$b"

   does not have such a problem.

This patch series is a result of the discussion at [1].

Patrick
