"Typical workflow" observations on Windows

[adswa]

As I have a Win 10 Pro build 2004 box for testing, @yarikoptic asked me to test the "Typical Workflow" from the README on Windows.

I'm testing under two different terminals/shells: A Git Bash and an Anaconda Prompt (both installed using the most recent instructions from the handbook).

Unfortunately, testing required more time than I anticipated, so I'm posting the issue "as is", although I haven't finished the workflow. I will return to this at a later point.

Git Bash:

• Pro: Copy-pasting the script directly into the terminal works because Git Bash supports multi-line commands
• datalad run -m 'Downgrade/Freeze mriqc container version' containers/scripts/freeze_versions bids-mriqc=0.15.1 fails when copy-pasting and when executing in a script with:

> datalad run -m 'Downgrade/Freeze mriqc container version' containers/scripts/freeze_versions bids-mriqc=0.15.1
[INFO] == Command start (output follows) =====
'"containers/scripts/freeze_versions"' is not recognized as an internal or external command,
operable program or batch file.
[INFO] == Command exit (modification check follows) =====
[INFO] The command had a non-zero exit code. If this is expected, you can save the changes with 'datalad save -d . -r -F .git\COMMIT_EDITMSG'
CommandError: '"containers/scripts/freeze_versions" "bids-mriqc=0.15.1"' failed with exitcode 1 under C:/Users/datalad/AppData/Local/Temp/repro-x8Gb5J4/ds000003-qc

A fix for this would be to invoke datalad run with bash <script>:

datalad@latitude-e7440 MINGW64 /tmp/repro-Yo4XEyy/ds000003-qc (adjusted/master(unlocked))
$ datalad run -m "Downgrade/Freeze mriqc container version" bash containers/scripts/freeze_versions bids-mriqc=0.15.1
[INFO] == Command start (output follows) =====
I: bids-mriqc -> 0.15.1
[INFO] == Command exit (modification check follows) =====

Anaconda Prompt:

• Fail: You can't copy paste the command into the terminal. I believe Windows needs ^ at each line ending in multi-line commands (see the last Windows-Workaround in this section
• I can't currently say definite things about what happens when I execute the script via "bash " in Anaconda prompt, because I'm seeing a very weird interaction between Windows and WSL2, where a bash session from Windows ends up in WSL2:

(base) C:\Users\datalad\repos>echo "This is anaconda prompt on native Windows 10!"
"This is anaconda prompt on native Windows 10!"

(base) C:\Users\datalad\repos>echo %username%
datalad

(base) C:\Users\datalad\repos>bash
adina@latitude-e7440:/mnt/c/Users/datalad/repos$ groups
adina adm cdrom sudo dip plugdev
adina@latitude-e7440:/mnt/c/Users/datalad/repos$ echo "WTAF"
WTAF
adina@latitude-e7440:/mnt/c/Users/datalad/repos$

I need to redo this after wiping the machine again.
