Pass the editor name to the shell if it contains any susv3 shell
special character (globs, redirections, variable substitutions,
escapes, etc). This way, the meaning of some characters will not
meaninglessly change when others are added, and git commands
implemented in C and in shell scripts will interpret editor names
in the same way.
This does not make the GIT_EDITOR setting any more expressive,
since one could always use single quotes to force the editor to
be passed to the shell.

Many call sites use strbuf_init(&foo, 0) to initialize local
strbuf variable "foo" which has not been accessed since its
declaration. These can be replaced with a static initialization
using the STRBUF_INIT macro which is just as readable, saves a
function call, and takes up fewer lines.

This patch removes exit()/die() calls and builtin-specific messages
from launch_editor(), so that it can be used as a general libgit.a
function to launch an editor.

launch_editor() is declared in strbuf.h but defined in builtin-tag.c.
This patch moves launch_editor() into a new source file editor.c,
but keeps the declaration in strbuf.h.
