From: Derrick Stolee <dsto...@microsoft.com>
The first consumer of pattern-matching filenames was the
.gitignore feature. In that context, storing a list of patterns
as a 'struct exclude_list' makes sense. However, the
sparse-checkout feature then adopted these structures and methods,
but with the opposite meaning: these patterns match the files
that should be included!
It would be clearer to rename this entire library as a "pattern
matching" library, and the callers apply exclusion/inclusion
logic accordingly based on their needs.
This commit replaces 'EXCL_FLAG_' to 'PATTERN_FLAG_' in the
names of the flags used on 'struct path_pattern'.
