[PATCH 06/13] perf ui browser: Introduce ui_browser__write_nstring()
From: Arnaldo Carvalho de Melo
Date: Wed Aug 12 2015 - 12:43:16 EST
From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>
To remove direct access to libslang functions, with the immediate goal
of implementing horizontal scrolling at the ui_browser level, but also
because we may at some point want to implement ui_browser with other UIs
in addition to the current libslang implementation.
