I agree with the idea that you shouldn't get used to behaviour that
isn't common on different boxes, but my change doesn't affect the
semantic content of the command at all. The following commands achieve
the same thing (where /home/roydsd is my home directory):
ls ~/Documents
ls /home/roydsd/Documents
My proposed change just alters what happens to Tab completion. On
another machine, I'll get a wee surprise when Bash changes the ~ to
/home/whoever, but the command will still work.
The tilde still works on my machine.

Douglas,
I "like" the idea that one can customize their computer to do whatever.
However, you have the problem:
what happens when you have to use someone else's computer. Most likely
they will have bash as the default shell, and ~ will work in the way you
dislike
When someone else uses your computer - they will complain that the ~
symbol don't work.
I would have thought that using \~ will get most circumstances.

It has irritated me for some time that Bash was expanding ~ (my home directory
path). For instance, if I type:
$ ls ~/Doc <Tab>
Bash would expand the path to:
$ ls /home/roydsd/Documents
This is a matter of personal taste, but I'd prefer the tilde to remain,
thanks.
I've found the culprit in /etc/bash_completion. Find the function _expand(),
and edit it as follows:
# This function expands tildes in pathnames
#
_expand()
{
[ "$cur" != "${cur%\\}" ] && cur="$cur\\"
# expand ~username type directory specifications
if [[ "$cur" == \~*/* ]]; then
#eval cur=$cur <-------- Commented out
return # <-------- Added
elif [[ "$cur" == \~* ]]; then
#cur=${cur#\~} <-------- Commented out
#COMPREPLY=( $( compgen -P '~' -u $cur ) ) <--------
Commented out
#return [EMAIL PROTECTED] <-------- Commented out
return # <-------- Added
fi
}
