+Each line in a `gitignore` file specifies a pattern.
When deciding whether to ignore a path, git normally checks
`gitignore` patterns from multiple sources, with the following
order of precedence, from highest to lowest (within one level of
`core.excludesfile` in the user's `~/.gitconfig`.
The underlying git plumbing tools, such as
-linkgit:git-ls-files[1] and linkgit:git-read-tree[1], read
+'git-ls-files' and 'git-read-tree', read
`gitignore` patterns specified by command-line options, or from
files specified by command-line options. Higher-level git
-tools, such as linkgit:git-status[1] and linkgit:git-add[1],
+tools, such as 'git-status' and 'git-add',
use patterns from the sources specified above.
Patterns have the following format:
