`tooltip-use-echo-area' is obsolete since 24.1; disabling `tooltip-mode'
achieves similar effect, and Tooltip mode has already been disabled in the
current code. Since Spacemacs supports Emacs 24.3 and 24.4,
`tooltip-use-echo-area' usage can be removed safely.
Not sure why that part of code was introduced in the first place but it seems to no longer work with the newest
packages. Both backtick and quote behaviors were a kind of broken. Removing the code makes them normal again. And there
seems to be nothing wrong with Github code blocks.
I have seen many "I have a problem" discussions in the Gitter chat which
starts with a barrage of questions "Which OS? Which Emacs version?",
etc., so I thought it may be useful to have one function that will
generate the info to be copy-pasted into the Gitter chat and hence both
the user and others helping in the Gitter chat can jump directly to
solving the problem instead of the support volley to figure out the
setup.
Example output:
ELISP> (spacemacs/system-info)

The ess company sources should be grouped, when they are not grouped
they are pretty buggy (like not showing completions under certain
circumstances).
To see the problem, try opening an R file and start the interpreter.
When you type the following ([] is the cursor):
setN[]
You will see completions offering up `setNames`. Press `<enter>`.
Now, try doing the following:
setNames(setN[])
You will see no completions. Company is trying the `company-R-args`
source, failing it, then skipping the execution of the
`company-R-objects` source.
Grouping them together fixes this, and is what's done within ess itself.
This variable allows to put the point behind the last
character of a line in normal state.
So now eval-last-sexp behaves as expected in elisp and all
other languages.
Note that this is not the default in Vim but it does not
make a lot of sense to force this behavior in Emacs where
eval-last-sexp is so important.
Anyway it is easy to revert the behavior by setting this
variable back to nil in dotspacemacs/config
