[PATCH] quotearg: add quotearg_n_style_colon()

From: Pádraig Brady
Subject: [PATCH] quotearg: add quotearg_n_style_colon()
Date: Wed, 4 Nov 2015 23:17:48 +0000

This quotes with default options of the specified style,
but with quoting enabled for instances of ':'.

While this can be simulated by temporarily modifying
the default quoting style, this is a little awkward,
and care must be taken with such an implementation
to avoid inlining leading to bloated text.

* lib/quotearg.h (quotearg_n_style_colon): Description and declaration.
* lib/quotearg.c (quotearg_n_style_colon): New function implementation.
