Log Message:
PR lib/54510: Fix file completion inside quotes which broke in rev 1.53
While there also fix handling character appending in the file completions when
inside quotes. For example when inside a quote, if the completion is a
directory then
append a '/' but don't close the quote. On the other hand when inside a quote
if the
completion is a file name and it is the only match then we can close the quote.
