We have deprecated the old environment variable names for quite a
while and now it's time to remove them. Gone are:
SHA1_FILE_DIRECTORIES AUTHOR_DATE AUTHOR_EMAIL AUTHOR_NAME
COMMIT_AUTHOR_EMAIL COMMIT_AUTHOR_NAME SHA1_FILE_DIRECTORY

* I'm tired of doing "vsnprintf()" etc just to open a
|
|
* file, so here's a "return static buffer with printf"
|
|
* interface for paths.
|
|
*
|
|
* It's obviously not thread-safe. Sue me. But it's quite
|
|
* useful for doing things like
|
|
*
|
|
* f = open(mkpath("%s/%s.git", base, name), O_RDONLY);
|
|
*
|
|
* which is what it's designed for.
