Initial installer .profile syntax is not POSIX compatible

1

I noticed that .profile is modified by the rustup installer and adds

source "$HOME/.cargo/env"

While this works with bash (which is most of us here) it is a bashism and .profile isn't bash specific. There would no downside of using

. "$HOME/.cargo/env"

which would make it usable across all POSIX shells.

Just saying

Good catch! It looks like this was fixed recently, and the fix will be included in the next version of rustup:

Oops, I missed that it was already reported
