description:
make(1): fix documentation of VarParseErrors

It does not matter whether lint mode is enabled or not, Var_Parse must
reliably return whether an error message has been printed or not.

In the current phase where proper error handling is implemented only in
lint mode, this leads to code that looks a bit bloated since a few extra
branches are added, but that's ok.  Eventually the SILENT constants will
all be removed, and then the number of different cases will shrink
again.
