Closing the log window with :q! remove syntax highlighting

[Olical]

As reported by Max Savchenko on Discord:

I'm observing strange behaviour: if I close conjure buffer with :q! and then open a new one—it lacks syntax colors although it has ft=clojure in it. it gets fixed with :set ft=clojure

if i close buffer with g:conjure#mapping#log_close_visible everything is fine of course

I suspect the ! suffix is killing the buffer in some way, or maybe clearing it's buffer local settings without deleting the buffer. It's some sort of half dead state so Conjure isn't re-creating the buffer with all of the right options set in this case like it normally would.

Interestingly, bdelete doesn't cause this issue. quit is fine too, it's only quit! that seems to break the buffer. The :help on this call is:

:q[uit]!		Quit without writing, also when the current buffer has
			changes.  The buffer is unloaded, also when it has
			'hidden' set.
			If this is the last window and there is a modified
			hidden buffer, the current buffer is abandoned and the
			first changed hidden buffer becomes the current
			buffer.
			Use ":qall!" to exit always.

It mentions that it unloads a buffer even if it has hidden set. So maybe it's "unloading" and not deleting the buffer?

Yep! :bunload reproduces the issue too! So we just have to check if the buffer is loaded or not. If it's not then we need to re-initialise.

thanks for taking care of this!
