BASH PATCH REPORT
|
|
=================
|
|
|
|
Bash-Release: 4.4
|
|
Patch-ID: bash44-007
|
|
|
|
Bug-Reported-by: Jens Heyens <jens.heyens@cispa.saarland>
|
|
Bug-Reference-ID:
|
|
Bug-Reference-URL: https://savannah.gnu.org/support/?109224
|
|
|
|
Bug-Description:
|
|
|
|
When performing filename completion, bash dequotes the directory name being
|
|
completed, which can result in match failures and potential unwanted
|
|
expansion.
|
|
|
|
Patch (apply with `patch -p0'):
