alias.fish: unbreak listing aliases without backslashes The description for an alias which already has escape sequences will use backslash escapes for quoting; usually `string escape` can simply quote it. Use a regex that accepts either escaping style.

alias: Use `read --tokenize` This did some weird unescaping to try to extract the first word. So we're now more likely to be *correct*, and the alias benchmark is about 20% *faster*. Call it a win-win.

alias d "'/mnt/c/Program Files (x86)/devenv.exe' /Edit"
functions d
Print nicer "defined in" for functions defined on stdin/via source This would tell you a function was "Defined in - @ line 1" for every function defined via `source`. Really, ideally we'd figure out where the *source* call was, but that' much more complicated, so we just give a comprehensible message.

alias: don't add --wraps for wrappers with the same name These aliases seem to be common, see #7389 and others. This prevents recursion on that example, so `alias ssh "env TERM=screen ssh"` will just have the same completions as ssh. Checking the last token is a heuristic which hopefully works for most cases. Users are encouraged to use functions instead of aliases.
