Follow-up to #10626: parse_signer_source rejects valid keypair file paths containing spaces
Even with quotes in shell, some CLI commands (e.g. solana transfer --keypair "C:\My Folder\id.json") fail parsing.
My Proposals -
- Update CliSigners / DefaultSigner to trim/ handle quoted paths more robustly.
- Or add shell escaping note in error message.
- Test case: Add unit test for path with space.
Happy to attempt a PR if maintainers confirm the direction.
