If you mean specificall the dash, I can't help much. But there were
similar ideas elsewhere. UNIVAC EXEC-8 (for the 1108, late 1960s) had
options that followed the command with a comma, like:
@ADD,PL ASGDMS . ASSIGNIERT DATENBASIS
@ASG,A PF. . PF IST PROGRAMM-FILE MIT GOPU
The letters after the comma were option letters, conveniently packed
into a machine word so that they didn't require parsing.
OMEGA on the Univac 494 had something similar, but delimited by a
space rather than a comma, reminiscent of earlier tar syntax.
I don't know any other systems, but since UNIVAC and Unix aren't
closely related, I'd guess that there were similar ideas elsewhere
