Subject: lib: add notmuch_thread_get_total_files
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=50340bcb78586dc63b5e0914563665b30e8f88d0;p=notmuch.git

lib: add notmuch_thread_get_total_files

This is relatively inexpensive in terms of run time and implementation
cost as we are already traversing the list of messages in a thread.
