@ -57,6 +57,13 @@ Patterns have the following format:
|
||||
included again. If a negated pattern matches, this will
|
||||
override lower precedence patterns sources.
|
||||
|
||||
- If the pattern ends with a slash, it is removed for the
|
||||
purpose of the following description, but it would only find
|
||||
a match with a directory. In other words, `foo/` will match a
|
||||
directory `foo` and paths underneath it, but will not match a
|
||||
regular file or a symbolic link `foo` (this is consistent
|
||||
with the way how pathspec works in general in git).
|
||||
|
||||
- If the pattern does not contain a slash '/', git treats it as
|
||||
a shell glob pattern and checks for a match against the
|
||||
pathname without leading directories.
