Hey Tim,
Please see http://savannah.gnu.org/bugs/?31781 where it implemented. Since
version 1.12.1.
On my personal mac I have 1.19.5, and when I run the command with both
arguments i get:
"Both --no-clobber and --convert-links were specified, only --convert-links
will be used."
As a response.
Anyway, I might make due without -nc if I can use the regex argument. Could you
give an example on how would that argument work in my case? Can I just use
www.mywiki.com/delete/* as an argument for example? or .*/xpage=watch.* ?
Thanks!
