Actually maybe not that short.  The string with all the filenames is 38k
characters.  I'm not sure when exactly grep starts failing, but it takes 2
invocations of grep to process that string, so 32k sounds entirely
plausible.  I'm using cygwin grep with NTEmacs with "c:\cygwin\bin\zsh.exe"
as my shell, if that's relevant.

Since I already have the list of files, doing grep this way is really fast.
 I don't expect this is a use-case that comes up often for everyone, but if
anyone looks for something similar in the future, hopefully this helps.

Also, despite what I've implied, Emacs' grep family of functions have very
good support for whitespaces.  Sorry about the confusion.
