Retrieve Beyond Compare's path from registry
Switch from a hardcoded path to registry key to find Beyond Compare's
executable. Calling BCompare.exe works fine with version 3.0.14.
#!/bin/sh
hg init
echo This is file a1 > a
hg add a
hg commit -m "commit #0" -d "1000000 0"
ls
echo This is file b1 > b
hg add b
hg commit -m "commit #1" -d "1000000 0"
hg co 0
# B should disappear
ls
