Improve the HISTORY sections of glob(7) and glob(3).

1. Make /etc/glob history less wordy and more precise: it was already in v1.

2. Remove the incorrect statement that the Bourne shell first integrated
globbing.  The PWB shell already did that in mid-1975, i.e. a least a few
months before Stephen R. Bourne started working on his shell, and the PWB
shell was publicly released with PWB/UNIX 1.0 about two years before v7.

3) The "PWB Shell" first appeared in mid-1975.

4) The Bourne shell work started either in early 1976, or maybe late 1975.

In "The UNIX Shell", Stephen R. Bourne says:
"The design of the shell is based in part on the original UNIX shell
and the PWB/UNIX shell, some features having been taken from both."

3. Avoid the confusing statement that the glob() function first appeared
in 4.4BSD.  Actually, the PWB shell, the Bourne shell (in v7), the first
UCB shell (in 1BSD), and the C shell (in 2BSD) all contained internal
functions either called "glob()" or at least containing "glob" as a part
of their function name.

4. Be more precise regarding when the current functions first appeared:
they were already in Reno.
