sequencer.c: drop 'const' from function return type

gitster · gitster · commit ee5462d6e71a · 2017-12-27T11:12:45.000-08:00
With -Werror=ignored-qualifiers, a function that claims to return
"const char" gets this error:

    CC sequencer.o
sequencer.c:798:19: error: type qualifiers ignored on function return
type [-Werror=ignored-qualifiers]
 static const char command_to_char(const enum todo_command command)
                   ^
