|
|
# an acceptable trailer key are preserved, but any other lines have their content removed
|
|
# (leaving a blank line).
|
|
#
|
|
# This works because the first .* (inside capture group 1) only matches if the line starts
|
|
# with a trailer key. If it doesn't, then the line is fully consumed by the second .*
|
|
# (which is outside the capture group, and therefore $1 is empty).

# STEP 4: If there are trailer lines (ie. if the first line has a newline followed by more
|
|
# text), then add an extra blank line after the first line, ie. to separate the commit's
|
|
# trailers from the subject line.
|
|
#
|
|
# The first capture group (^.*?\n) is the first line (non-greedily consuming chars until a
|
|
# newline), while the second capture group ((\n|.)*) is the rest of the message (greedily
|
|
# consume all chars, including newlines).

# chars, and so the pattern will fail to match.
