Michael Kuhn 67ab73d381 fetch_strategy: improve GitFetchStrategy (#10153) ... Currently, only the Git repsository's URL shows up in the `spack info` output, which makes it hard to distinguish different versions: ``` Safe versions: develop [git] https://github.com/LLNL/H5Z-ZFP.git 0.8.0 [git] https://github.com/LLNL/H5Z-ZFP.git 0.7.0 [git] https://github.com/LLNL/H5Z-ZFP.git ``` This change adds additional information as shown when cloning a Git repository: ``` Safe versions: develop [git] https://github.com/LLNL/H5Z-ZFP.git on branch master 0.8.0 [git] https://github.com/LLNL/H5Z-ZFP.git at commit af165c4 0.7.0 [git] https://github.com/LLNL/H5Z-ZFP.git at commit 58ac811 ```		2018-12-19 14:33:58 -08:00
