Subject: Move launch_editor() from builtin-tag.c to editor.c
X-Git-Tag: v1.6.0-rc1~38
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=d82f33e20dcf068e679eff2a16ecf8fe7b10fb31;p=git.git

Move launch_editor() from builtin-tag.c to editor.c

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.
