Long bibtex files are slow due to show-smartparens-mode

[jcpetkovich]

I get an enormous amount of lag when viewing bibtex files using show-smartparens-mode. Turning it off eliminates the lag.

To reproduce:

1. clone development version of spacemacs
2. run spacemacs without a .spacemacs file
3. open a large bibtex file.
4. search for something with C-s or similar.

I have experienced something similar. With a 100K emacs lisp file(auto generated file), while navigating and encounter a big block with ')', it is slow.

I don't want to modify the spacemacs/packages.el file, which has a (show-smartparens-global-mode +1). I have to exclude the smartparens package from .spacemacs.

I want to know if there is a configuration to disable show-smartparens-mode. Or it would be better if spacemacs can stop searching matching parens if out of the screen.
Adding (show-smartparens-global-mode nil) to dotspacemacs/config does not disable it.

@pennyan The mode is enabled unless the argument is a negative integer, you need (show-smartparens-global-mode -1).

You can now open large files with SPC f l, which will disable all special behaviour, including what causes this problem.

There is a feature planned in #3491 (comment) to include an automatic prompt for this, as well.

With that in mind I'm closing this issue.
