Redirection errors terminate the containing subshell (and shell)

[ko1nksm]

$ touch /tmp/dummy

$ brush --version
brush 0.2.14 (git:dd1d39c)

$ brush -c 'set -C; (: > /tmp/dummy); echo reach here'
ERROR error: failed to redirect to /tmp/dummy: File exists (os error 17)

$ bash -c 'set -C; (: > /tmp/dummy); echo reach here'
bash: line 1: /tmp/dummy: cannot overwrite existing file
reach here

This is a good find, thanks for the clear steps.

It looks like this more broadly applies to redirection errors, e.g.:

$ brush -c ': >/non/existent; echo hi'
ERROR error: failed to redirect to /non/existent: No such file or directory (os error 2)

$ bash -c ': >/non/existent; echo hi'
bash: line 1: /non/existent: No such file or directory
hi

We will need to ensure these errors are recoverable, and will neither cause the subshell nor the shell to exit.
