- Add official patch bash50-004
* In bash-5.0, the `wait' builtin without arguments waits for all children of the
shell. This includes children it `inherited' at shell invocation time. This
patch modifies the behavior to not wait for these inherited children, some
of which might be long-lived.
- Add official patch bash50-005
* In certain cases, bash optimizes out a fork() call too early and prevents
traps from running.
- Add official patch bash50-006
* Bash-5.0 did not build successfully if SYSLOG_HISTORY was defined without
also defining SYSLOG_SHOPT.
- Add official patch bash50-007
* Running `exec' when job control was disabled, even temporarily, but after it
had been initialized, could leave the terminal in the wrong process group for
the executed process.
