Subject: bug#58133: 29.0.50; Tramp do not parse auth-sources
Date: Mon, 10 Oct 2022 21:55:23 +0800

Dear all,

This happened from the commit be2e6228f8c9c57d2809bdd953d065ebfc63d4c4 (Aug 26) in which the
`tramp-completion-file-name-handler` becames:

"\\`\\(?:\\`[[:alpha:]]:\\)?\\(?:^/\\)\\(?:\\(?:\\(?5:-\\|[[:alnum:]]\\{2,\\}\\)\\(?::\\)\\(?:\\(?:\\(?6:[^/:|[:blank:]]+\\)\\(?:@\\)\\)?\\(?:\\(?7:\\(?:[%._[:alnum:]-]+\\|\\(?:\\[\\)\\(?:\\(?:[[:alnum:]]*:\\)+[.[:alnum:]]*\\)?\\(?:]\\)\\)\\(?:\\(?:#\\)\\(?:[[:digit:]]+\\)\\)?\\)\\)?\\)\\)\\(?:|\\)\\)*\\(?:\\(?:-\\|[[:alnum:]]+\\)\\(?:\\(?::\\)\\(?:[%._[:alnum:]-]+\\)?\\)?\\)?\\'"

Before that the `tramp-completion-file-name-handler` (b7e867b841f47dcff3aeaef9b5608a237386ce70, Aug 23) is

"\\`\\(?:[[:alpha:]]:\\)?/\\(\\([^/|:]+:[^/|:]*|\\)*\\(-\\|[^/|:]\\{2,\\}\\)\\(:[^/|:]*\\)?\\)?\\'"

which works. And if I run

```
(add-to-list
 'file-name-handler-alist
 (cons "\\`\\(?:[[:alpha:]]:\\)?/\\(\\([^/|:]+:[^/|:]*|\\)*\\(-\\|[^/|:]\\{2,\\}\\)\\(:[^/|:]*\\)?\\)?\\'"  #'tramp-completion-file-name-handler))
```

then tramp can make completion, e.g., when I do `find-file` and input
"/", the tramp-methods will come to the completion list.
