Improved `NIX_SSHOPTS` parsing for better SSH option handling
5181
12020

The parsing of the NIX_SSHOPTS environment variable has been improved to handle spaces and quotes correctly. Previously, incorrectly split SSH options could cause failures in CLIs like nix-copy-closure, especially when using complex ssh invocations such as -o ProxyCommand="ssh -W %h:%p ...".

This change introduces a shellSplitString function to ensure that NIX_SSHOPTS is parsed in a manner consistent with shell behavior, addressing common parsing errors.

For example, the following now works as expected:

export NIX_SSHOPTS='-o ProxyCommand="ssh -W %h:%p ..."'

This update improves the reliability of SSH-related operations using NIX_SSHOPTS across Nix CLIs.
