dojo: simplify dir not exist error message build
Incorporates suggested changes (thanks!).
Drops the path serialization as it will print on two separate lines,
and it is already displayed in dojo immediately above the error message:
> =dir /=base=/ge
dojo: dir does not exist
?: ?=([@ @ ~] pax) ~[i.pax i.t.pax '0']
pax
?: =(~ .^((list path) %ct pax))
- =- +>(..dy (he-diff %tan - ~))
- rose+[" " `~]^~[leaf+"dir does not exist:" (smyt pax)]
+ +(..dy (he-diff %tan 'dojo: dir does not exist' ~))
=. dir (need (de-beam pax))
=- +>(..dy (he-diff %tan - ~))
rose+[" " `~]^~[leaf+"=%" (smyt (en-beam he-beak s.dir))]
