When I run a git command I often get
sh: line 0: igncr: invalid option name
As output. This is caused by a setting I have to make cygwin tolerable. IT looks like git is spawning a sh process to run in. Can I configure this to be a bash shell instead?
It doesn't add much but as requested here is the git command
gt ad -p A/B/C.csproj
The shell commands causing failure are
export SHELLOPTS
set -o igncr

Please run the failing git command prefixed with GIT_TRACE=1 to see the details of the failing shell command spawned, and take it from there...
EDIT: After seeing the trace, given the fact that igncr is a cygwin specific bash option, consider adding a bash function to override the gt command and turn off that shell option.
For example,
gt () { (set +o igncr; git "$@";) }
gt ls-files
of course you should move the gt function to your .bashrc or similar.
