[texhax] Regarding {BEFORESKIP}{AFTERSKIP}{ parameters in \@startsection

[Philip TAYLOR (Webmaster, Ret'd)]

There was an over-simplification in my previous reply.
Where I wrote :

this is true only for BEFORESKIP.  For AFTERSKIP, a leading "-"
indicates that the heading is to be run-in, and the absolute
value indicates the skip to leave to the right of the run-in
heading.  I don't think this has any material impact on
my recommendations (as opposed to my commentary) but it should
be borne in mind when setting AFTERSKIP to non-zero values.
