lynx-dev memory leak in LYHistory.c

[Leonid Pauzner]

While running with LY_FIND_LEAKS a memory leak discovered somethere in the
"history stack". It may be seen when you follow deep into the links
and then press PREV_DOC key several times (as much as possible).

This probably related to 2001-02-26 track record - no more changes in this
area during the last 4 years or so.  Since the invention of "nhist_extra"
I do not understand this code any more.


2001-02-26 (2.8.4dev.19)
...
* implement an action NEXT_DOC, which undoes what PREV_DOC (usually on the
  Left-arrow key) does -IZ
  Possible enhancements:
  a) make HISTORY show the position on the (no more!) "stack".
  b) several places in the source use the value of nhist (they scan
     history?).  Make nhist_extra public, and check whether these
     places want nhist + nhist_extra instead.
  c) Currently LYpop() and (some) LYpush() erases "the tail" of the
     stack.  Maybe some callers would prefer a different semantic...
