Documentation

Default user to use for specific method/host pairs.

This is an alist of items (METHOD HOST USER). The first matching item specifies the user to use for a file name which does not specify a user. METHOD and HOST are regular expressions or nil, which is interpreted as a regular expression which always matches. If no entry matches, the variable tramp-default-user takes effect.

If the file name does not specify the method, lookup is done using the empty string for the method name.

Probably introduced at or before Emacs version 23.1.
