Support for git describe abbrev length

[martinmosegaard]

Since Git 2.11, the default abbreviation length is no longer always 7 digits. This means that the output of a plain git describe may vary. To get consistent behavior, we can use git describe --abbrev=N. But that does not seem to be supported by grgit.describe.

I am not familiar with jgit and whether this feature request should be reported there.

This issue seems related: #238
and I am able to get a specific number of digits with the getAbbreviatedId function like: grgit.head().getAbbreviatedId(7).

For background on the Git change, see:

It doesn't look like JGit's DescribeCommand supports specifying a fixed length for the abbreviated sha. If you happen to open an issue (or find one already open), please link it here so we can monitor the progress.

Thanks for the help with JGit. I have opened https://bugs.eclipse.org/bugs/show_bug.cgi?id=537883 for JGit.

Thanks for reminding me, I had completely forgotten to comment back here after I add this upstream 😉

As is now noted in the readme this plugin is feature frozen. No new features will be added.
