[Agda] More aggressive `with`: Please check your Agda-2.4.2 developments!

[Andreas Abel]

Dear Agda users and developers,

please check your larger Agda-2.4.2 developments with the version at

   https://github.com/andreasabel/agda-issue-1692/tree/maint-2.4.2

You can get it with

   git clone https://github.com/andreasabel/agda-issue-1692.git
   cd agda-issue-1692
   git checkout maint-2.4.2
   make install-bin

This version is making `with` more agressive and hopefully more 
intuitive (at least it removes the stumbling block reported in issue #1692).

The change is not fully backwards compatible. However, the breakage 
should be small. Nothing broke for the std-lib. Only a single test case 
broke, which uses with on a function argument (a variable):
https://github.com/agda/agda/blob/master/test/lib-succeed/Issue846/DivModUtils.agda#L99
The breakage was easy to fix, the new `with` is simpler: the `with` on 
the variable could be removed.

Please check the amount of breakage on your Agda developments and report 
back, with self-contained test-cases (e.g. as tar-balls and repo links) on

   https://github.com/agda/agda/issues/1692

This let's me evaluate whether this commit can go into the maintenance 
version or not (in case the breakage is too big).

Response time: 5 work days.

Cheers,
Andreas
