\overline and subscripts/superscripts in mathtext #5444
Description
The following code works fine in matplotlib 1.4.3, but it fails in matplotlib 1.5.0.
import matplotlib.pyplot as plt
ax = plt.subplot(111)
ax.plot([0,1],[0,1])
ax.text(0.5, 0.5, r'$\overline{\omega}$')
ax.text(0.5, 0.6, r'$\overline{\omega}^x$')
ax.text(0.5, 0.4, r'$\overline{\omega}_x$')
The traceback is super long, but here is the last line.
File "/Users/Ben/Library/Enthought/Canopy_64bit/User/lib/python2.7/site-packages/matplotlib/mathtext.py", line 2809, in subsuper
last_char.width = last_char._metrics.advance
AttributeError: 'Vlist' object has no attribute '_metrics'

Only check _metrics of subsuper nucleus if available

Well, that's embarrassing. We were definitely missing a test for a
VlistorHlistas last character of the subsuper nucleus. I have added a fix against master in #5448, but should definitely be backported to 1.5.x.mdboom commentedon Nov 9, 2015
No worries. The only people who never break code are people who never submit code ;) Thanks for the quick fix.
