- With this patch, the empty path (empty element in PATH or PATH is

It might be a good idea to include a comment in the code and the commit message
that this feature is being added for Linux compatibility but that it is
deprecated. According to https://man7.org/linux/man-pages/man7/environ.7.html,
As a legacy feature, a zero-length prefix (specified as
two adjacent colons, or an initial or terminating colon)
is interpreted to mean the current working directory.
However, use of this feature is deprecated, and POSIX
notes that a conforming application shall use an explicit
pathname (e.g., .) to specify the current working
directory.
Alternatively, maybe this is a case where we should prefer POSIX compliance to
Linux compatibility. Corinna, WDYT?
