Yes, a command that returns false is not a fatal error. In the
meantime you can do this to work around the problem.
% { $(< foo) }; echo hello
zsh: no such file or directory: foo
% { $(< foo) } always { TRY_BLOCK_ERROR=0 }; echo hello
zsh: no such file or directory: foo
hello

eg, call vcs_info inside the first { }. However, I'm not sure how to
make the construct return false when it failed with a fatal error.
