It looks like the tab complete in 1.4 is a bit broken for the show command; for example, here's what happens when I try to tab complete with 1 tab
[email protected]:~$ show protocols Possible completions: bfd static
If you notice, it does not show my shell prompt again, it leaves my cursor hanging at the end of the last line above. and if use a double-tab it does:
[email protected]:~$ show protocols Possible completions: bfd static Possible completions: bfd static [email protected]:~$ show protocols
The correct behavior can be seen in 1.3 with 1 tab
[email protected]:~$ show protocols Possible completions: bfd static [email protected]:~$ show protocols
