(Help, mainline code): Add new option -L FILE.

(Copyright): Update year.

(LANG, LANGUAGE, LC_ALL, LC_COLLATE, LC_CTYPE, LC_MESSAGES,
LC_NUMERIC, LC_TIME): New shell vars, to make sure we live in the C locale.

(mainline code): Handle nonstandard -u option differently, by
transforming it to standard form.  Check for "Working file: ", not
"Working file:".  Allow file names with spaces.

(SOH, rlogfile): New shell vars.
(rlogout): Remove.  Its old functionality is mostly migrated to rlogfile.

Append ';;' to the last arm of every case statement, for portability to
ancient broken BSD shells.

(logins): Fix bug; was not being computed at all, lowering performance.

(pository): New var.  This fixes some bugs where repositories are
remote, or have trailing slashes.

(authors): $llogout is never an empty shell var, so don't worry about that
possibility.

(printlogline, mainline code): Fix bug with SOH's being put into the output.
