Use case :
If a folder name starts with an undescore, Phonegap fails to load the contained files
Tested on the demos contained in jQM 1.2.0 Beta download :
docs/_assets/js/jqm-docs.js doesn't load whereas docs/assets/js/jqm-docs.js loads properly
Do you think this a problem with our code or something with PhoneGap? Hard to tell.
Actually it seems to come from Android (http://code.google.com/p/android/issues/detail?id=5343) but it is not obvious to find out when running jQM.
My suggestion would be to document it on jQM website and simply rename the "_assets" folder into "assets". This will save time for others.
Added note about underscores in PhoneGap for Android. Fixes #4991
