Update of bug #35063 (project make):

           Triage Status:                    None => Medium Effort          


Follow-up Comment #1:

A useful idea.  FMI:


Note we already have a $% variable (for archive members) and their associated
$(%D) and $(%F) (which are both legal hex values BTW).

So we will have to decide whether we'd prefer the "uncleanliness of
$(.%<token>), or the potential backward-compatibility issue with $(%xx)... as
long as we require two digits and don't allow omitting of the leading 0.

Also we should consider whether this encoding should be limited to the strict
URL restricted character set, or whether it will extend to any legal UTF-8
character with code <128.

We'd need to decide when the expansion is done.  Is it done using normal
expansion rules?  Or is it done very early by the makefile parser?
