|

# --modified: files tracked by git that have been modified (staged or unstaged)
|
|
# --exclude-standard: ignores files in .gitignore
|
|
# Additionally exclude files in 'lib/EpdFont/builtinFonts/' as they are script-generated.
|
|
# Also exclude files in 'lib/Epub/Epub/hyphenation/generated/' as they are script-generated.
|
|
# Keep the no-match case non-fatal: grep returns 1 when no files match,
|
|
# which is expected when there are no modified C/C++ files.
