The last time this came up, I wrote:
For historical reasons, complete/compgen dequote the filename they're
passed, removing backslash escapes and interpreting embedded quoted
substrings. (One of the things bash should do when it does that is to
be better about obeying the shell rules about backslash-escaped characters
and double quotes, but that doesn't matter for this example -- though that
function has several problems.)
When it's called as the result of readline dispatching on a particular
character, this is appropriate -- the shell hasn't done any expansion
or quote removal, so the filenames still have embedded quoting. When
called from the command line, as in these examples, it's not appropriate,
since the shell has already expanded the argument and stripped the
quotes.
