@erikw Hey, hope you're doing well. I just found a new bug.
You can clearly see that two files have been modified but the commit message has only 1.

$ git status --porcelain
M  Equal_Coins.cpp
 M Task.cpp

$ git commit-status
Modified: Equal_Coins.cpp 
> Commit with this message? [Y/n]:
n

Looks like there's a space before M Task.cpp that might be causing the issue, but why is there a space in the first place?
Please have a look.

• Update - Sorry my bad, I forgot to do git add . lol.

@isayakmondal Hello!

Yes I was just about to write that, that a space before means that the M is is for the file in the working area, not in the staged area (after git add).

Nevertheless, I started to look at this alias and felt a need to simplify it a bit. I worked out an updated version. As you are an active user of this one, would you mind trying if it works for you as well? It works when I've tested it, but it would be great to hear if it works also for at least another person!

Sorry for the late reply, this seems to work fine till now but the version with [Y/n] prompt is better.

@isayakmondal Thank you for testing. I added then [Yn] prompt to the Gist as well :)

If you want to add this alias as a oneliner from Powershell:
git config --global alias.cs "! TMPFILE=`$(mktemp /tmp/git-commit-status-message.XXX); git status --porcelain | grep '^[MARCDT]' | sort | sed -re 's/^([[:upper:]])[[:upper:]]?[[:space:]]+/\1:\n/' | awk '!x[`$0]++' | sed -re 's/^([[:upper:]]:)`$/\n\1/' | sed -re 's/^M:`$/Modified: /' | sed -re 's/^A:`$/Added: /' | sed -re 's/^R:`$/Renamed: /' | sed -re 's/^C:`$/Copied: /' | sed -re 's/^D:`$/Deleted: /' | sed -re 's/^T:`$/File Type Changed: /' | xargs > `$TMPFILE; git commit -F `$TMPFILE; rm -f `$TMPFILE"

Thanks at @tomeo. That's a pretty massive one-liner there 😄
