Release 1.1.1 2024-06-23

Changed LOCATION_VERSION to "1.0.4 2024-05-22".

Fixed usage string in location_main.c: it did not suggest that one can specify
more than one location but it can.

Added to the README.md brief documentation of the location(1) tool (it was not
there at all) and fixed some typos and added some clarity in the location.1
man page.

Updated the Rule 2a size from 4096 to 4993: a change that keeps the
"Rule 2b:Rule 2a" ratio (that was recently changed from 2053 to 2503)
similar to the 2001-2020 IOCCC era.
