When using `eval` a new scope named 'local' gets pushed for the
whole evaluation, this makes it possible to temporarily set
an option/hook/alias...
Local scopes nest so nested evals do work as expected.
Remove the now trivial with-option command
-verbatim will disable argument parsing in evaluate-commands, making
it possible to forward a single command to a different context without
triggering a reparsing of the arguments.
Fixes -try-client support in grep.kak
Closes#3153
Relevant filter in the code:
```
if (*bufnames == "*")
{
for (auto&& buffer : BufferManager::instance()
| transform(&std::unique_ptr<Buffer>::get)
| filter([](Buffer* buf) { return not (buf->flags() & Buffer::Flags::Debug); })
| gather<Vector<SafePtr<Buffer>>>()) // gather as we might be mutating the buffer list in the loop.
context_wrap_for_buffer(*buffer);
}
```
There does not seem to be any reasonable use cases of not collapsing
jumps when the input is not comming from the user. Always collapse
them.
It could make sense to move jump collapsing out of context_wrap as
in general any action not comming directly from the user should
collapse them, at the moment a comment or mapping will not collapse
jumps, which is unfortunate.
