Right, spaces require quotes in sh and lei inserts quotes when
it sees spaces assuming it's a phrase search.  Most queries
involving filenames don't have spaces, and your original query
shouldn't have spaces.  It's 3 separate args in @argv of
`lei_q': [ "dfn:COPYING", "OR", "dfn:Makefile" ]

In other words, no quotes or spaces are needed in your case at all:

$ lei q dfn:COPYING OR dfn:Makefile
(I've omitted the -I and -o args for brevity)

Your original query only passes 1 arg due to single or double quotes
handled in the shell (assuming POSIX-like sh or bash):

$ lei q 'dfn:COPYING OR dfn:Makefile' # don't do this
$ lei q "dfn:COPYING OR dfn:Makefile" # don't do this, either

In both cases the `lei_q' subroutine would only see
[ "dfn:COPYING OR dfn:Makefile" ] in its @argv.

If you have odd cases where you really need spaces in a single
token and maybe not phrase search, --stdin can probably get what
you want more reliably:

$ echo 'dfn:"some filename with spaces" AND something.else' | lei q --stdin

Hope that helps.
