You will still need to check for errors after performing any filesystem
operations. That would seem to be the place to check for permission
violations (along with all the other things that can go wrong when working
with the filesystem). That also helps reduce the probability of a race

By the way, the double-hyphen preceding the signature block is
traditionally followed by a single space.

(Why on earth would I notice this? Because my mail client automatically
trims off the signature block when replying to a message. But it only
does so it if matches /^--\s$/.)
