Special character sequences in git commands

[El-Gor-do]

This is for other people's future reference. I was using the MSBuildGitHash Nuget package v2.0.2.

While trying to run some custom git commands to capture additional information, I ran into problems with character sequences that needed to be escaped.

• % needs to be escaped as %%
• ae needs to be escaped as a%e
• cd needs to be escaped as c%d

These are the git commands I was trying to run:

• git show --quiet --format=%ae
• git show --quiet --format=%an
• git show --quiet --format=%cd --date=iso-strict
• git show --quiet --format=%B
• git show --quiet --format=%H

This is the corresponding ItemGroup with correctly escaped character sequences:

  <ItemGroup>
    <AssemblyMetadataCommand Include="GitAuthorEmail">
      <Command>git show --quiet --format=%%a%e</Command>
    </AssemblyMetadataCommand>
    <AssemblyMetadataCommand Include="GitAuthorName">
      <Command>git show --quiet --format=%%an</Command>
    </AssemblyMetadataCommand>
    <AssemblyMetadataCommand Include="GitCommitDate">
      <Command>git show --quiet --format=%%c%d --date=iso-strict</Command>
    </AssemblyMetadataCommand>
    <AssemblyMetadataCommand Include="GitCommitMessage">
      <Command>git show --quiet --format=%%B</Command>
    </AssemblyMetadataCommand>
    <AssemblyMetadataCommand Include="GitFullHash">
      <Command>git show --quiet --format=%%H</Command>
    </AssemblyMetadataCommand>
  </ItemGroup>

There may be other character sequences that require escaping which I am not yet aware of.

If you want to add a brief description about this to the readme.md, I will merge it.
