- Add patches 13-18 to bash-4.4-patches.tar.bz2
* 13: If a here-document contains a command substitution, the
command substitution can get access to the file descriptor used
to write the here-document.
* 14: Under some circumstances, functions that return via the
`return' builtin do not clean up memory they allocated to keep
track of FIFOs.
* 15: Process substitution can leak internal quoting to the
parser in the invoked subshell.
* 16: Bash can perform trap processing while reading command
substitution output instead of waiting until the command
completes.
* 17: There is a memory leak when `read -e' is used to read a
line using readline.
* 18: Under certain circumstances (e.g., reading from /dev/zero),
read(2) will not return -1 even when interrupted by a signal.
The read builtin needs to check for signals in this case.
