Description Joachim Backes 2011-08-29 18:24:49 UTC 
Description of problem:
Suppose you have a file called ":1" (touch :1)
Then the command "rm :<tab>" completes to "rm :\:" which is wrong because :1 contains only one colon (not two).

Version-Release number of selected component (if applicable):
bash-4.2.10-4.fc16.x86_64

How reproducible:
always

Steps to Reproduce:
1.See description
2.
3.
  
Actual results:
See description

Expected results:
Completion to "rm :1" or at least to "rm \:1"

Additional info:
1. The F16 behaviour differs from the F15 behaviour.
2. I think it nothing to do with the fact that the bash command ":" does nothing.
Comment 1 Roman Rakus 2011-08-30 13:56:18 UTC 
Not a bug. bash's readline have special variable COMP_WORDBREAKS. `:' is considered as word separator.
Comment 2 Joachim Backes 2011-08-30 14:24:23 UTC 
echo $COMP_WORDBREAKS 
"'><=;|&(:
unset COMP_WORDBREAKS

 
echo $COMP_WORDBREAKS 

Now ':' is no more a separator!

But still:

'rm :<TAB>' completes to 'rm :\:'

I think, the bug should be reopened!

COMP_WORDBREAKS loses special meaning when unset, see man page

Use something like
COMP_WORDBREAKS=${COMP_WORDBREAKS/:/}
