extensions: refactor function for obtaining disabled extension help...
extensions: refactor function for obtaining disabled extension help The way this worked before was hgext.__index__ was consulted. This file appears to only be present on some Windows distributions. This file contains a dict mapping extension name to its summary line, not its full docstring. The problem with this is that code in the help system was calling this function to resolve help text. If hgext.__index__ was present, only the summary line would be displayed. If not, the full extension help would be printed. This commit changes the function to not use hgext.__index__ such that it always returns the full extension help text. As a result of this change, test-extension.t and test-qrecord.t now pass when run from environments that have an hgext.__index__. Differential Revision: https://phab.mercurial-scm.org/D8344

Mercurial's default format for showing changes between two versions of
a file is compatible with the unified format of GNU diff, which can be
used by GNU patch and many other standard tools.
While this standard format is often enough, it does not encode the
following information:
- executable status and other permission bits
- copy or rename information
- changes in binary files
- creation or deletion of empty files
Mercurial also supports the extended diff format from the git VCS
which addresses these limitations. The git diff format is not produced
by default because a few widespread tools still do not understand this
format.
This means that when generating diffs from a Mercurial repository
(e.g. with :hg:`export`), you should be careful about things like file
copies and renames or other things mentioned above, because when
applying a standard diff to a different repository, this extra
information is lost. Mercurial's internal operations (like push and
pull) are not affected by this, because they use an internal binary
format for communicating changes.
To make Mercurial produce the git extended diff format, use the --git
option available for many commands, or set 'git = True' in the [diff]
section of your configuration file. You do not need to set this option
when importing diffs in this format or using them in the mq extension.
