crashes without mercurial installed

[matkoniecz]

On encoutering folder with .hg subfolder this script attempts to call mercurial. If mercurial is not installed (may be typical today as git seems to won version control wars) this script crashes.

I would expect error message or even better - complaint ans skipping over such repository.

To reproduce - uninstall mercurial (if any is available), create folder, create subfolder named .hg, call this script to check location where test folder were created.

I gues that it is caused by folder with unsufficient rights. I would expect it to handle it gracefully and skip folder
