BASH PATCH REPORT
=================
Bash-Release: 5.0
Patch-ID: bash50-002
Bug-Reported-by: Ante Peric <synthmeat@gmail.com>
Bug-Reference-ID: <B7E3B567-2467-4F7B-B6B9-CA4E75A9C93F@gmail.com>

Bug-Description:
When an alias value ends with an unquoted literal tab (not part of a quoted
string or comment), alias expansion cannot correctly detect the end of the
alias value after expanding it.
