I'll not argue whether such a feature would make sense or not, or
whether it can be implemented, because it is aimed at the user, but
misses one important point: It does in no way help our development process.

A patch auther whose first instinct is to write 'foo=/' will never write
'foo=x', let alone 'foo="""/"""'. Someone will have to discover the
issue eventually and write a patch to fix it, and someone will have to
apply it.

I don't think that we can do anything about it.
