If the path to the wiredtiger build directory contains the wiredtiger ticket number referenced by the checked out branch s_mentions will spit out pages and pages of "mentions".

The following steps can be taken to reproduce this issue:

1. Git clone wiredtiger into a directory with a ticket number as its name e.g. wt-9000
2. Build the code in build/ or cmake_build/ or build_cmake/
3. git checkout a "fix" branch, "wt-9000-fix"
4. Run ./s_mentions.

We should fix the script to ignore build directories when running.
