I still can't reproduce it on Mac OS X or RHEL 5.7:
$ echo $BASH_VERSION
4.2.20(8)-release
$ type -a compspec_foo
compspec_foo is a function
compspec_foo ()
{
local cmd=$1 cur=$2 pre=$3;
if [[ $cur = :* ]]; then
COMPREPLY=(changed changed/IGNORE_ME);
fi
}
$ complete
complete -F compspec_foo foo
$ set -x
$ COMP_WORDBREAKS=${COMP_WORDBREAKS%?}
+ COMP_WORDBREAKS='
"'\''@><=;|&('
$ echo $COMP_WORDBREAKS
+ echo '"'\''@><=;|&('
"'@><=;|&(
$ foo :this-is-a-+ local cmd=foo cur=:this-is-a- pre=foo
+ [[ :this-is-a- = :* ]]
+ COMPREPLY=(changed changed/IGNORE_ME)
changed
+ foo changed
bash: foo: command not found
$ foo :this-is-a-long-word+ local cmd=foo cur=:this-is-a-long-word pre=foo
+ [[ :this-is-a-long-word = :* ]]
+ COMPREPLY=(changed changed/IGNORE_ME)
changed
+ foo changed
bash: foo: command not found
I wonder if there's some difference in our environments that's the cause.
