Bug 111467

Description of problem:
The pdksh does not escape spaces or other special characters when
doing filename completion, as in bash.  For example, under bash:

$ ls
My Documents/ foo bar
$ cd M[TAB]

the directory name will be expanded with the space escaped:

$ cd My\ Documents/
$

Using pdksh, the filename is successfully completed, but the space is
not escaped (vi line editing mode shown):

$ cd M[Meta-\]

results in:

$ cd My Documents/
ksh: cd: bad substitution
$

Version-Release number of selected component (if applicable):
pdksh-5.2.14-23

How reproducible:
Always

Steps to Reproduce:
1. Execute /bin/ksh (pdksh)
2. Execute `echo bar > "file with spaces"`
3. Execute `cat fil[Meta-\]` (or whatever key sequence you have chosen
to do filename completion in pdksh; this depends on the line editing
mode you choose. in vi mode, this is Meta-\)

    

Actual Results:  Note that without manually escaping the spaces or
enclosing the entire filename in quotes, the contents of the file will
not be displayed with the error:

cat: file: No such file or directory

because the filename is expanded without escaping the spaces:

$ cat file with spaces

Expected Results:  As in bash, the spaces at least should be escaped
for convenience and security reasons.

$ cat fil[Meta-\]

should result in the following completion:

$ cat file\ with\ spaces

Additional info:

I seem to be the only person who cares about this.  However, it is a
bug and should be fixed :-)

Note the following url, I have one lone sympathizer who noticed this
bug in NetBSD and submitted a partial patch (only works in vi
line-editing mode):
