[PATCH v2] Add script to get modified pages for commit msgs

The script can be used this way:

git commit -sm "$(./scripts/modified_pages.sh): Short commit msg"

And then maybe --ammend and add a longer message.

This is especially useful for changes to many pages at once,
usually when running a script to apply some global changes.

Now it will also include new files and deleted files.

+## Usage:
+## git commit -m "$(./scripts/modified_pages.sh): Short message here"
+##
+## How it works:
+## 1) Read git status.
+## 2) Staged changes are always before "Changes not staged for commit".
+## Cut from that point to not include pages not staged for commit.
+## 3) Keep only lines containing "modified:" or "deleted:" or "new file:"
+## (each of those is a changed file)
+## 4) Keep only the path, replacing git text by ", ".
+## 5) Keep only the basenames of the files in 'man?/'.
+## 6) Remove any newline characters.
+## 7) Remove the comma before the first file
+##
+## The result is a list of all files with changes staged for commit,
+## separated by ", ".
+

+git status \
+|sed "/Changes not staged for commit:/q" \
+|grep -E "^\s*(modified|deleted|new file):" \
+|sed "s/^.*:\s*/, /" \
+|sed "s%man[1-9]/%%" \
+|tr -d '\n' \
+|sed "s/^, //"
