Subject: [PATCHv2 3/5] revision.c: stricter parsing of '--early-output'
Date: Fri, 9 Jun 2017 20:17:31 +0200 [thread overview]
Message-ID: <20170609181733.6793-4-szeder.dev@gmail.com> (raw)
In-Reply-To: <20170609181733.6793-1-szeder.dev@gmail.com>
The parsing of '--early-output' with or without its optional integer
argument allowed bogus options like '--early-output-foobarbaz' to slip
through and be ignored.
Fix it by parsing '--early-output' in the same way as other options
with an optional argument are parsed. Furthermore, use strtoul_ui()
to parse the optional integer argument and to refuse negative numbers.
While at it, use skip_prefix() instead of starts_with() and magic
numbers.
