largefiles: align the output messages for an added file with core methods

Core addremove prints the file relative to cwd only if patterns are provided to
the command.  Core add always prints relative to cwd.  Also, both methods print
the subrepo prefix when needed.  The 'already a largefile' doesn't have an
analog in core, but follows the same rules for consistency.

When Mercurial accepts more than one revision, they may be specified
individually, or provided as a topologically continuous range,
separated by the ":" character.

The syntax of range notation is [BEGIN]:[END], where BEGIN and END are
revision identifiers. Both BEGIN and END are optional. If BEGIN is not
specified, it defaults to revision number 0. If END is not specified,
it defaults to the tip. The range ":" thus means "all revisions".

If BEGIN is greater than END, revisions are treated in reverse order.

A range acts as a closed interval. This means that a range of 3:5
gives 3, 4 and 5. Similarly, a range of 9:6 gives 9, 8, 7, and 6.
