You should certainly write a PR for the former. For the latter, seeing

is perfectly `reasonable' in the Unix sense of the term. :-) EPERM
is the correct error for the system to return when you attempt to
remove a file that's immutable. The two options to make this message
`better' are to add a brand new error EPERMIMU `Attempt to remove
an immutable file' (or some such), which is a bit silly, or to have
rm check the flags on the file every time an EPERM is returned to
see if the file is immutable and in a directory that the current
user has wx access to, which also gets a bit silly.
