When `log --decorate` is used, git will decorate commits with all available refs. While in most cases this may give the desired effect, under some conditions it can lead to excessively verbose output. Introduce two command line options, `--decorate-refs=<pattern>` and `--decorate-refs-exclude=<pattern>` to allow the user to select which refs are used in decoration. When "--decorate-refs=<pattern>" is given, only the refs that match the pattern are used in decoration. The refs that match the pattern when "--decorate-refs-exclude=<pattern>" is given, are never used in decoration. These options follow the same convention for mixing negative and positive patterns across the system, assuming that the inclusive default is to match all refs available. (1) if there is no positive pattern given, pretend as if an inclusive default positive pattern was given; (2) for each candidate, reject it if it matches no positive pattern, or if it matches any one of the negative patterns. The rules for what is considered a match are slightly different from the rules used elsewhere. Commands like `log --glob` assume a trailing '/*' when glob chars are not present in the pattern. This makes it difficult to specify a single ref. On the other hand, commands like `describe --match --all` allow specifying exact refs, but do not have the convenience of allowing "shorthand refs" like 'refs/heads' or 'heads' to refer to 'refs/heads/*'. The commands introduced in this patch consider a match if: (a) the pattern contains globs chars, and regular pattern matching returns a match. (b) the pattern does not contain glob chars, and ref '<pattern>' exists, or if ref exists under '<pattern>/' This allows both behaviours (allowing single refs and shorthand refs) yet remaining compatible with existent commands.
