This is a no-bug. Posix.2 says:
3.14.4 dot - Execute commands in current environment
. file
The shell shall execute commands from the file in the current
environment.
(NB: no mention about arguments, here's the part of the rationale:)
The KornShell version of dot takes optional arguments that are set to the 1
positional parameters. This is a valid extension that allows a dot 1
script to behave identically to a function.
So if someone cares to implement it, we are free to do it, but it's
not strictly a bug, and your shell programs cannot be considered
portable if they use this feature.
I tend to move this PR into the `suspended' state, so it could be
closed in case somebody offers an implementation, but i'm rather
afraid that nobody will still know the PR by that time. Right now,
there are many actual bugs waiting to be fixed, so i would not give
this any priority.
Probably i will close it, and if somebody feels adventurous to
implement it, he can submit this as a followup to this PR anyway
(GNATS will notice it and record it in the PR).
