Re: [Ctags] new language regular expression

[Darren H. <dhi...@us...>]

Joseph,

As Elliot pointed out, the best way is to put the '-' as either the first or 
last character of a the "list" operator (i.e. "[...]"). The '-' character 
cannot be escapes with the list operator. For a description of the "range 
operator" (i.e. '-'), see:
