[tex-live] Missing files in "comprehensive"

[jack]

After a "tlmgr update", it looks like the "comprehensive" package is
missing the PDF file called "symbols-letter.pdf".

I hope this is an accidental oversight and not on purpose.  Its twin
"symbols-a4.pdf" (which is still there) is inconvenient for those of us in
the USA, and also, on a laptop screen it's too small to comfortably read
when zoomed in such a way that the whole page is on the screen at once.

It looks like nothing else changed in the package except the removal of
two other PDF files.
