bll 2017-9-20 This widget keeps the native directory name and the normalized directory name separate so that the native name is displayed and the normalized name is used in the -textvariable variable.
Update: Figured out how to display the Mac OS X localized names. Mac OS X has some localized files such as 'French.strings' instead of 'fr.strings' (See $HOME/Music/iTunes/iTunes Media/Automatically Add to iTunes.localized/.localized/). I put a list of some of those names in, but don't know if it is complete. It is rather inefficient, but there doesn't seem to be a programmatic way to get these localized names from a command line program. I also plan on adjusting my file/directory choosers to use the routines made available here to display the localized names.
The path is semi-normalized -- symlinks are kept intact.
