commit b05752c223b79f3b42fb2a506377fc12adaf8aeb
Author: Keith Seitz <keiths@redhat.com>
Date:   Thu Feb 24 16:42:22 2022 -0800

    Unit tests for strncmp_iw_with_mode
    
    This patch attempts to make a start at adding unit tests for
    strncmp_iw_with_mode.  While there is quite a bit of testing
    of this function in other tests, these are currently end-to-end
    tests.
    
    This patch attempts to cover the basics of string matching, white
    space, C++ ABI tags, and several other topics. However, one area
    that is ostensibly missing is testing the `match_for_lcd' feature.
    This is otherwise tested as part of our end-to-end DejaGNU-based
    testing.
