[PATCH v6 1/7] sq_quote_argv: drop maxlen parameter

[Nguyễn Thái Ngọc Duy]

From: Jeff King <p...@peff.net>

No caller passes anything but "0" for this parameter, which
requests that the function ignore it completely. In fact, in
all of history there was only one such caller, and it went
away in 7f51f8bc2b (alias: use run_command api to execute
aliases, 2011-01-07).
