I think leaders are meant to be used in conjunction with
diversions.  When they are used in already formatted text,
all required dimensions are known, allowing n/troff to
compute the number of leader character repetitions plus any
possibly required additional space.  See the attached example.
Note that "\t" has one backslash, so it is evaluated as a
tab while the diversion is being set up (the input is the
"input line"), but "\\a" has two backslashes, so the leaders
are applied when the diversion is output to the page (the
formatted content of the diversion is the "input line").
