Subject: [PATCH 01/15] for-each-ref, quote: convert *_quote_print -> *_quote_buf
Date: Tue,  9 Jul 2013 16:02:12 +0530	[thread overview]
Message-ID: <1373365946-9230-2-git-send-email-artagnon@gmail.com> (raw)
In-Reply-To: <1373365946-9230-1-git-send-email-artagnon@gmail.com>

From: Nguyễn Thái Ngọc Duy <pclouds@gmail.com>

for-each-ref.c:print_value() currently prints values to stdout
immediately using {sq|perl|python|tcl}_quote_print, giving us no
opportunity to do any further processing.  In preparation for getting
print_value() to accept an additional strbuf argument to write to,
convert the *_quote_print functions and callers to *_quote_buf.

[rr: commit message, minor modifications]
