fe315a25c4 Recognize internal variables new in bash 5.3 
From the bug-bash@gnu.org announcement "Bash-5.3-beta available":

    q. GLOBSORT: new variable to specify how to sort the results of
       pathname expansion (name, size, blocks, mtime, atime, ctime,
       none) in ascending or descending order.

    w. BASH_MONOSECONDS: new dynamic variable that returns the value of
       the system's monotonic clock, if one is available.

    x. BASH_TRAPSIG: new variable, set to the numeric signal number of
       the trap being executed while it's running.
