Periodically skip :! spam. This is a "cheat" that works for all UIs and greatly
improves responsiveness when :! spams MB or GB of output:
:!yes
:!while true; do date; done
:!git grep ''
:grep -r '' *
After ~10KB of data is seen from a single :! invocation, output will be skipped
for ~1s and three dots "..." will pulse in the bottom-left. Thereafter the
behavior alternates at every:
* 10KB received
* ~1s throttled
This also avoids out-of-memory which could happen with large :! outputs.
Note: This commit does not change the behavior of execute(':!foo').
execute(':!foo') returns the string ':!foo^M', it captures *only* Vim
messages, *not* shell command output. Vim behaves the same way.
Use system('foo') for capturing shell command output.
Closes #1234
