[ANNOUNCE] tig-0.13

Hello,

This release contains a major rewrite of the IO layer of tig to use fork+exec instead of popen() and remove use of stdio's fopen() and friends. The new IO API removes the need for shell quoting and improves the overall speed of loading view data. On the downside, it brings a few incompatibilities wrt. commands given via the environment. While the patch series began by being based on git's run-command.c module, the final version contains no code from git.

The release also brings a few new features, such as new identifiers for use in external commands as well as a handful of bug fixes.

What is tig? ------------ Tig is an ncurses-based text-mode interface for git. It functions mainly as a git repository browser, but can also assist in staging changes for commit at chunk level and act as a pager for output from various git commands.

Release notes ------------- Incompatibilities:

 - Commands from the environment (e.g. TIG_MAIN_CMD) will no longer have
   access to shell features, such as subshells and variable expansion.
   The easiest way to upgrade your configuration is to put such commands
   in a script file.

Improvements:

 - Display repository references in the sorted order: tags, heads,
   tracked remotes, remotes.
 - Add bash completion for blame.
 - Tree view: edit files of the current branch.
 - Run requests: new identifiers %(directory), %(file), and %(ref)
 - Improve responsiveness and view loading speed by using select(2).

Bug fixes:

 - Separate blame revision and file argument by "--" to avoid problems.
 - Main view: fix redrawing of the last commit wrt. the revision graph.
 - Fix waiting for input after executing a run request in pager mode.
 - Status & stage view: refuse to open directories and deleted files.
 - Tree view: show error when requesting blame for all non-file entries.
 - Do not draw loading views, which are not displayed.
 - Fix launching of mergetool from a subdirectory.
