Subject: [PATCH 4/4] smbclient: Fix recursive mget
Make do_mget rely on do_list() already doing the recursion in a
breadth-first manner. The previous code called do_list() from within
its callback. Unfortunately the recent simplifications of do_list()
broke this, leading to recursive mget to segfault. Instead of figuring
out how this worked before the simplifications in do_list() (I did
spend a few hours on this) and fixing it, I chose to restructure
do_mget() to not recursively call do_list() anymore but instead rely
on do_list() to do the recursion. Saves quite a few lines of code and
complexity.
