Show path-separator error for all patterns containing '/', not just directories

[danielalanbates]

Summary

The "pattern contains path separator" error was only shown when the pattern also happened to be an existing directory (e.g., fd Programs/ where Programs/ exists). Patterns like fd foo/bar that aren't directories silently returned no results with no diagnostic.

Now the error is always shown when the pattern contains a path separator and --full-path is not used. The "search inside directory" suggestion is conditionally shown only when the pattern is an actual directory.

Example

Before (pattern is not a directory — no error, silent empty results):

$ fd foo/bar
$

After:

$ fd foo/bar
[fd error]: The search pattern 'foo/bar' contains a path-separation character ('/') and will not lead to any search results.

If you want your pattern to match the full file path, use:

  fd --full-path 'foo/bar'

There is already a PR for this.

This also doesn't update the changelog, or add any tests.

And it doesn't address the issue that on windows the path separator is also the regex escape character.

Thanks for pointing out the existing PR. Apologies for the duplicate!
