Repro steps.

1. ng new repro-app
2. ng build -bh /testing/
3. look at your /dist/index.html and see that the base tag looks as follows

   <base href="C:/Program Files/Git/testing/">

notice it has added the local directory to Git for some reason.

Desired functionality.

when using --base-href the value specified in the base element of index.html should be exactly the text typed in following the --base-href flag.

Try something like: ng build -bh="testing" or ng build --base-ref="testing"

It seems to be an issue when running the command in git bash the same command works properly in powershell.

[tolgabalci]

It's not an issue, its a feature of git bash on Windows. It's trying to help you out by converting Linux paths to Windows paths.

You can tell git bash to avoid the conversion for the -bh parameter by setting the MSYS2_ARG_CONV_EXCL environment variable while calling ng like this:
MSYS2_ARG_CONV_EXCL="-bh=" ng build --prod -bh="/en/"

Note that to use the exclusion you must use -bh parameter with an =, not space since MSYS2_ARG_CONV_EXCL will think the value after the space is a different parameter.
