389 | Notes: | |
390 | Using "-f directory" may give unexpected results: | |
391 | Used with "--git", git signators for _all_ files in and below | |
392 | directory are examined as git recurses directories. | |
393 | Any specified X: (exclude) pattern matches are _not_ ignored. | |
394 | Used with "--nogit", directory is used as a pattern match, | |
395 | no individual file within the directory or subdirectory | |
396 | is matched. | |
397 | Used with "--git-blame", does not iterate all files in directory | |
398 | Using "--git-blame" is slow and may add old committers and authors | |
399 | that are no longer active maintainers to the output. | |
