fdisk: autocomplete for loading script file adds space to suggested filename

[castilma]

How to reproduce:

$ echo foo >script.sfdisk
$ head -c 1K /dev/zero >img
$ fdisk img
## press I
## type script<Tab>
##  you should see script.sfdisk being suggested. press enter.

result:

Welcome to fdisk (util-linux 2.39.3).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Device does not contain a recognized partition table.
Created a new DOS (MBR) disklabel with disk identifier 0x4656ec7a.

Command (m for help): I

Enter script file name: script.sfdisk 
Cannot open script.sfdisk : No such file or directory

Command (m for help): 

For this bad script file I expect:

Command (m for help): I 

Enter script file name: script.sfdisk 
Cannot open script.sfdisk: Invalid argument

A solution might be setting rl_completion_append_character to \0, or rl_completion_suppress_append to non-zero.

Would you like to send a patch (pull request)?

I never programmed with readline. Can't be too difficult. Probably it belongs into one of the few HAVE_LIBREADLINE occurrences. I'll look in the next few days, whether I'm able to do that. If I don't respond after that, assume I couldn't do it.
