Beware that the bash mailing list also has a usenet interface

Great website (http://wiki.bash-hackers.org) explaining the changes in bash-4.*

In the past, I've scanned Bash's ChangeLog and it didn't provide any meaningful
explanations, just very brief details.

Hi!
If the current word on the command line contains a shell variable, then
the expansion works as if the variable had been expanded, but then
quotes the variable. An example is probably a lot better than theory:
Steps to reproduce
1. Type "echo $HOME/.bas"
2. Press tab
3. Press tab again
Actual
Hi!
I often get a bash message about new mail during command line completion.
Steps to reproduce:
Type "ls ~/.bas" and press tab.
Expected result:
Command line completed to "ls ~/.bash" or whatever is right.
Actual result:
If new mails have arrived, the mail check is performed when pressing
tab

Sorry for the delay.
I've applied your expr-noeval.patch file to the bash-4.2.10-4.fc15 package
