Partial filename matching results in unused files being ignored

[davidgreen99]

I have a repo containing two PNG files which are sitting in a 'media' folder but which are not referenced by any markdown (.md) files in the repo.
For some reason, these two unused files are NOT being detected as unused. Instead they are listed as used.
When I look in the files which FindUnusedFiles says references them, I find only references to similar files with names which contain the files which are not used.

e.g. unused file connect.png is reported as used in 'auto-client'reconnect-policy-settings.md':

BUT 'auto-client'reconnect-policy-settings.md' references a different file whose name includes the :
![Auto client reconnect image](/en-us/xenapp-and-xendesktop/current-release/media/auto-client-reconnect.png)

Is there a way to force FindUnusedFiles to match full filenames only?
