[tex-live] Please don't assume case sensitive file system

[Akira Kakuto]

In the directory trunk/Master/texmf-dist/doc/latex/bclogo/
of the TL repository, there are files
bcIcosaedre.eps, bcIcosaedre.pdf and
bcicosaedre.eps, bcicosaedre.pdf.

Therefore, I cannot check out the Master due to
a fatal error.
Please tell the author not to use such names.

Thanks,
Akira
