help: show help for disabled extensions (
issue5228)
This patch does not exactly solve
issue5228 but it results in a better
condition on this issue. For disabled extensions, we used to parse the
module and get the first occurrences of docstring and then return the first
line of that as an introductory heading of extension. This is what we get
today.
This patch returns the whole docstring of the module as a help for extension,
which is more informative. There are some modules which don't have much
docstring at top level except the heading so those are unaffected by this
change. To follow the existing trend of showing commands either we have to
load the extension or have a very ugly parsing method which don't even assure
correctness.

If you can't run the entire testsuite for some reason (it can be
difficult on Windows), please at least run `contrib/check-code.py` on
any files you've modified and run `python contrib/check-commit` on any
commits you've made (for example, `python contrib/check-commit
273ce12ad8f1` will report some style violations on a very old commit).
