BASH PATCH REPORT
=================
Bash-Release: 5.0
Patch-ID: bash50-001
Bug-Reported-by: axel@freakout.de
Bug-Reference-ID: <201901082050.x08KoShS006731@bongo.freakout.de>
Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2019-01/msg00079.html
Bug-Description:
Under certain circumstances, the glob expansion code did not remove
backslashes escaping characters in directory names (or portions of a
pattern preceding a slash).
Patch (apply with `patch -p0'):
