------------

Patch 7.0.060 (after 7.0.51)
Problem:    Code for temporarily switching to another buffer is duplicated in
	    quite a few places.
Solution:   Use aucmd_prepbuf() and aucmd_restbuf() also when FEAT_AUTOCMD is
	    not defined.
Files:	    src/buffer.c, src/eval.c, src/fileio.c, src/if_ruby.c,
	    src/if_perl.xs, src/quickfix.c, src/structs.h
