In dvc-status mode, L runs dvc-log, which is declared as:
(defun dvc-log (&optional path last-n)
"Display the brief log for PATH (a file-name; default current
buffer file name; nil means entire tree; prefix arg means prompt
for tree), LAST-N entries (default `dvc-log-last-n'; all if
nil). Use `dvc-changelog' for the full log."
(interactive (list (if current-prefix-arg nil (buffer-file-name))
dvc-log-last-n))
'last-n' should always default to dvc-log-last-n.
Are you familiar with running lisp code in the interactive debugger?
Open dvc-unified.el, put point anywhere in the definition of dvc-log,
and type C-M-x; that "instruments dvc-log for debugging". Then invoke
it as you normally do; it will single step thru the function. Use
<space> to step, e to evaluate a symbol; examine last-n at the
invocation of dvc-call "dvc-log".
If that's ok, the next step is to debug xhg-dvc-log, defined in
xhg-revision.el as:
(defun xhg-dvc-log (path last-n)
"Show a dvc formatted log for xhg."
(interactive (list default-directory nil))
this always defaults last-n to nil when run directly, but that should
not matter when it is called from dvc-log.

This should work.

This runs dvc-changelog, which provides no mechanism to set last-n, so
that won't work either.
I don't have xhg installed, so I can't effectively debug this.

That's sad.
