Tim had previously pointed my attention to this package:
http://cran.r-project.org/web/packages/HGNChelper/index.html

which has a function called `findExcelGeneSymbols` with the following
description:

"""
This function identifies gene symbols which may have been
mogrified by Excel or other spreadsheet programs.  If output is
assigned to a variable, it returns a vector of the same length
where symbols which could be mapped have been mapped.
"""

I've never used it, so I'm not sure how well it works or not -- I
mean, I wouldn't trust it, but gotta give credit to the author for
trying :-)
