[Bug-zile] [PATCH 2/2] refactor: no need to consecutively reclear the minibuf.

[Gary V. Vaughan]

This seems to reduce CPU load by about 75% when pasting a large
amount of text, and is worth applying independently of whether
my previous patch makes sense, I think...

* src/minibuf.c (minibuf_clear): If the minibuf is already clear,
avoid re-clearing it.
