Log Message:
make(1): add more detailed debug logging for variable modifiers

Before a modifier is applied to a variable, it is not yet parsed,
therefore it is only possible to log a rough estimate of the modifier.
But after applying it, the parsing position has advanced, and the full
modifier can be logged.

In addition, to fully understand how the modifiers work, it's not enough
to just know the variable names and values, there are also some flags
that influence how the modifiers behave.  The most influential is
VARE_WANTRES.

Thanks to sjg for the extensive review and valuable feedback on the
first drafts.
