Details:

ms defines the leader character, for use within tables of contents generated
by XS/XA, as:

.char \[toc*leader-char] .\h'1m'

Personally, (and this is, strictly, just my opinion),  I think that 1em of
space between the leader dots is too much.  Unfortunately, that definition of
'toc*leader-char' appears within the body of the PX macro, (which is used to
emit the collected table of contents), so even knowing the (undocumented)
internal name, I cannot easily override the hard-wired definition.

I would like to apply a patch, such as the attached, so that users will have
an opportunity to adjust the leader style, and the width of the width of the
following right-hand margin, (in which the page number is placed), by defining
TC-LEADER and TC-MARGIN respectively, (both of which we can document),
_before_ invoking PX; (in the event of neither being predefined, the behaviour
would remain _identically_ as at present).
