description:
Summary: Remove over-simplified extraneous test

The file name matching code in libedit tries to adjust to the presence
of explicit " or ' characters in the input line, but tries too hard.
Remove a conditional that goes overboard, and causes the completion
code to fail if a quoted string is seen before the filename to be
expanded, as in

          grep 'foo' bar<TAB>

Before this change, the above would not expand any possible
completions, even if they existed, because it would choose to look for
files whose names started with " bar".
