Build fails if git config log.showSignature true

[RussKie]

All of a sudden my project failed to build with the following error:

Obviously when solution is compiled, GitInfo emits incorrect info.
\obj\Debug\GitInfo.cache:

Running the git log command in bash produces the following result:

    Merge pull request #5821 from xxx/feature/5811

    Fixed #5811: strange resize of the description column when selecting lines with mouse click

When git config log.showSignature false, the correct info is emitted:

GitBranch=test1;
GitCommit=33015f037;
GitSha=33015f03791b2441e3b5f997cc33a72af4862f11;

Expected:
I think you should set git config log.showSignature false (if it is set to true) when you're gathering information, and restore it back, when done.

I think you should set git config log.showSignature false (if it is set to true) when you're gathering information, and restore it back, when done.

Or use:

git -c log.showSignature=false log -n 1

Thanks for reporting and suggesting a clean fix!
