Comments, irrespective of whether they start with '#' or ';' are now treated the same. Otherwise, sections and key-value pairs with a trailing comment starting with ';' are still parsed. Consider this example: [some.section] # inline comment after section foo = bar ; inline comment after value The '[some.section]' section in the example above would otherwise not be parsed at all, while in the key-value definition 'foo' parses as the key, which is correct, but 'bar ; inline comment after value' parses as value, which is incorrect according to Ceph's grammar [0][1]. 2. Sections may now contain any character, including whitespace, but not '\n' or a comment literal '#' or ';'. The case for comment literals is handled in 1. above. 3. Instead of treating '-', '_' and ' ' as the same, only '_' and ' ' are treated the same, like in Ceph's parser [2]. 4. Comment literals ('#', ';') now are preserved when escaped via a backslash '\' [3].
