helm-gtags and ggtags are clients for GNU Global. GNU Global is a source
code tagging system that allows querying symbol locations in source
code, such as definitions or references. Currently, helm-gtags with GNU
Global is faster than anything else in Emacs for retrieving a large
amount of candidates (even more than 10000 candidates, the list appears
in an instant) and offers more features for language that GNU Global
directly: C, C++, Yacc, Java, PHP4 and assembly.
ggtags is nice for its eldoc support such as display variable/function
definition retrieved from the tag database. However, we disable ggtags
in some modes because those modes have better eldoc integration
already. We add ggtags for this feature alone.

With gh-md, it can use Github API to render HTML to be viewed right
inside Emacs using eww web browser. It is especially useful since it
does not required markdown-mode to be installed. One benefit is that it
automatically open the rendered buffer in other window, so for example
user is learning Clojure mode and want to read documentation of Clojure
layer, he will just simply fired up helm-spacemacs, narrow to `clojure`
and press RET. Then a nicely formatted documentation buffer appears on
the right side with all the key bindings of that layer, which greatly
enhances the explorability of Spacemacs.
Aside from cpp, better enable c++-mode in .h file since C is a subset of
C++ anyway. Without it, when entering .h file of C++, syntax
highlighting is wrong.
Currently, `r` and `p` moves to different locations when the change log
text is folded/unfolded. Make it always jumps to the correct location
regardless of content of home buffer by actually search for it.
Also set keys to make home buffer usable with holy-mode.
