- Update to bash 5.0 (final)
a. Tilde expansion isn't performed on indexed array subscripts, even for
backwards compatibility.
b. The shell doesn't exit in posix mode if the eval builtin gets a parse
error when run by the command builtin.
c. Fixed a bug that caused a shell comment in an alias to not find the end
of the alias properly.
d. Reverted a change from April, 2018 that caused strings containing
backslashes to be flagged as glob patterns.

- Update to bash 5.0 rc1
a. Fix to initial word completion detection code.
b. Fixed a bug that caused issues with assignment statements containing ^A in
the value assigned when IFS contains ^A.
c. Added a fallback to fnmatch() when strcoll can't correctly deal with
bracket expression character equivalence classes.
d. Fixed a bug that caused $BASH_COMMAND to contain the trap handler command
when running a trap handler containing [[ or (( commands.
e. Fixed a bug that caused nameref assignments in the temporary environment
to potentially create variables with invalid names.
f. Fixed a bug that caused `local -' to turn off alias expansion in scripts.
g. Fixed a parser issue with a command string containing EOF after an invalid
command as an argument to a special builtin not causing a posix-mode shell
to exit.
h. Made a slight change to the FNV-1 string hash algorithm used for associative
arrays (corrected the initial seed).
