linecache only for JRuby uses entries which only exists on String in 1.8...

... (Enumerable no longer mixed into string). This adds a reasonably compatible version.

I admit this is a little crappy. I could try and submit this to linecache, but linecache is stated that it will not work in 1.9, but we don't actually use the native extension part of linecache in JRuby. Adding this tiny monkey patch fixes things adequately for JRuby. Also, this version of ruby-debug is nearly as green as the 1.8 version, so I would like to minimally patch this gem for JRuby can have a working ruby-debug gem which works regardless of which mode is used: --1.8,--1.9,or --2.0.

That's a pretty awkward monkey patch.

I wonder how hard it would be to dump the linecache dependency entirely. It seems to be a headache.

[enebo]

Yeah. I tried to make something which would behave like entries in 1.8 for 1.9 mode but it does suck. I also thought about removing the dependency but the easiest way would be to use jruby-parser gem and that seemed somewhat heavy handed.

The second issue with linecache is there is a linecache and a linecache19 now :(

We can start with removing linecache dependency from ruby-debug-base. It's really needed only in ruby-debug
