Artificially limit the nesting of macro calls to @var{NUM} levels,
stopping program execution if this limit is ever exceeded. When not
-specified, nesting is limited to 1024 levels.
+specified, nesting is limited to 1024 levels. A value of zero means
+unlimited; but then heavily nested code could potentially cause a stack
+overflow. @var{NUM} can have an optional scaling suffix.
address@hidden FIXME - need a node on what scaling suffixes are supported (see
address@hidden [info coreutils 'block size'] for ideas), and need to consider
address@hidden whether builtins should also understand scaling suffixes:
address@hidden eval, mpeval, perhaps format
The precise effect of this option might be more correctly associated
with textual nesting than dynamic recursion. It has been useful

Restrict the size of the output generated by macro tracing or by
@code{dumpdef} to @var{NUM} characters per string. If unspecified or
zero, output is unlimited. @xref{Debug Levels}, for more details.
address@hidden can have an optional scaling suffix.
@comment FIXME - should we add a debuglen macro that can alter this
@comment setting on the fly? Also, should we add an option that
@comment controls whether output strings are sanitized with escape
@comment sequences, so that dumpdef is truly one line per macro?
address@hidden FIXME - see comment on --nesting-limit about NUM.
