changeset 227:8b1f6f6b6a3b

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Bugfixes: - Login and password are not always used now. Added new global variable to check it. - 'export PATH' is now only done if additional path(s) specified. Not really enhancements: - New coding style: - Local variables now start with double underscores and global variables start with single underscore. Both lower letter. - Function name is now snake_case. Camel_And_Snake_Case doesn't actually make sense :> - More comments. Still need to add even more comments.
