annotate src/org/tmatesoft/hg/repo/HgIgnore.java @ 356:91d75e1bac9f

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Consistent approach to deal with adaptable objects. Give adaptable precedence over instanceof to allow conditional response when classes do implement desired interface
