Yes, that was obvious from the beginning.

My question was why it was looking for egrep (in order to look for ispell).
There was a completion function defined for widget `color', and it wasn't
being called.

But I found my mistake - the defcustom was not defining the :type as
`color'. See my email to emacs-devel about that.

ispell-grep-command is "egrep", which is fine for me.

However, in emacs -Q, my usual PATH was not used (naturally), so it wasn't
found. Same thing occurs for `grep' or any other program. IOW, no problem
when my .emacs is used, because I set PATH there to include the cygwin
binaries, but emacs -Q has no idea about that (naturally).
