This commit introduces the `c_include_guard_style` option, which can
take one of the following values: "ifdef", "pragma", "none". The
corresponding type of guard will be used accordingly to the value of
this variable.
Centralize commenting functions into a single file, and declare
variables used by those functions in language support files. The
functions are `comment-selection` and `comment-line`, users should bind
those functions to the keys of their liking for easy access.
The modified files used to handle formatting code with the same code,
and a different command, the process is now centralized into a single
file. Language support files should set the `formatcmd` string to
whatever formatter is the most popular in their respective community,
eventually with default options.
Simplifies the selection commenting function, add proper draft options
to the exec statements, and make the uncommenting bit keep the selection.
Add a function that comments the current line with "//", uncommenting is
supported as well.
