Aha; I found obsolete text in one of my comments which likely
inspired this suspicion:

  /* If the line starts with + followed by whitespace, then
     it specifies that the targets are understood to be updated/created
     together by a single invocation of the recipe. In this case,
     we record a single entry for the first target which follows the +,
     and install the remaining targets as the also_make list of deps
     for that file, rather than iterating over the targets and 
replicating
     the rule for each one. */

All of that is incorrect.
