Actually, if you just enter the command git commit, an editor is opened where you can enter the commit message.
Alternatively, you can use the -m parameter to specify a commit header message at the command line, or even
multiple -m parameters to add several paragraphs. However, this doesn't easily let you insert line breaks in
at specific positions of a paragraph.
The following command can be used to "edit" a commit message on the command line, or in a script file:
git commit -F- <<EOF
Header of the message
Body of the message
with preformatted line breaks.
EOF
This is also suitable to specify a message for an annotated tag.
