Unhelpful shortcut parameters for git bash

When creating shortcuts for git bash on Windows machines, the "Target"
contains the command "C:\PF\Git\git-bash.exe --cd-to-home" and the
"Start In" field contains %HOMEDRIVE%%HOMEPATH%.

This is redundant, and makes it harder to modify the shortcut to start
bash in the user's directory of choice.

The option "--cd-to-home" should be removed. If was not present in 1.9.5
