I noticed some discrepancy in how files with ' or " are displayed. Is there a function that will automatically adjust the display of file names?

This is the output from GNU sort

$ sort --files0-from=- "ab"
sort: extra operand 'ab'
file operands cannot be combined with --files0-from
Try 'sort --help' for more information.

$ sort --files0-from=- "a'b"
sort: extra operand "a'b"
file operands cannot be combined with --files0-from
Try 'sort --help' for more information.

$ sort --files0-from=- "a'\"b"
sort: extra operand 'a'\''"b'
file operands cannot be combined with --files0-from
Try 'sort --help' for more information.

when opening a new PR, please do it with a clean list of commits "fix nul" or "fix empty" aren't great commit messages ;)

i guess you saw that some jobs failed

OsString.display() is too new (Rust 1.87), should I use OsString.debug() instead?
I ended up using PathBuf instead. As OsString.debug() adds extra "" around the string

OsString.display() is too new (Rust 1.87), should I use OsString.debug() instead?

Since the difference between an OsString and a regular String is only relevant with unprintable characters, we've just used to_string_lossy() for error cases (as well as non-error cases as a workaround hack when needed, but that's almost always a bug that will need to be fixed at some point). Might be a good idea to rely on display once MSRV is at least 1.87.
