GitCommit in commands package not being updated at build time

[johnmccabe]

Expected Behaviour

This results in the following output for a brew installed CLI:

$ ./faas-cli version
Git Commit: thisisavalidsha

Current Behaviour

Following the merge of #50 and the move of the GitCommit variable from the old main package rather than commands package this commit SHA isn't getting populated.

This results in the following output:

$ ./faas-cli version
Git Commit:

Possible Solution

Steps to Reproduce (for bugs)

1. Download the current 0.4.9 release, or build locally using build_redist.sh and run ./faas-cli version
