Summary

While working on a hg extension I've noticed that if SourceTree is using the embedded hg that sets a PATH in which the HG executable can't be found. It may think that the repository is a git repository and set the paths accordingly.

The output of echo $HG - $Path on commit hooks shows:

hg_local - /Applications/SourceTree.app/Contents/Resources/bin:/Applications/SourceTree.app/Contents/Resources/git_local/bin:/Applications/SourceTree.app/Contents/Resources/git_local/gitflow:/Applications/SourceTree.app/Contents/Resources/git_local/git-lfs:/usr/bin:/bin:/usr/sbin:/sbin:/usr/bin

Steps to Reproduce

1. Enable Always Display Full Console Output option
2. Navigate to Mercurial Repository
3. Add the code below in .hgrc

   [hooks]
   commit = echo $HG - $PATH
   

4. Make a commit on the mercurial repository
5. Observe the full console output
   
6. "hg_local" can't be located in the given PATH
