Display chained errors #43
Description
I'm trying to make norad cleanly chain errors instead of hoisting the error messages form lower into wrapping error messages. Compare what anyhow does:
Error: Failed to read glyph file from 'C:\...\MutatorSansLightWide.ufo\glyphs\A_.glif'
Caused by:
0: Failed to read or parse XML file
1: Expecting </array> found </dict>
vs. ufofmt's
[ERROR] norad read error: C:\...\MutatorSansLightWide.ufo: Failed to read glyph file from 'C:\...\MutatorSansLightWide.ufo\glyphs\A_.glif'
