dispatch: always load extensions before running shell aliases (
issue5230)
Before this patch, we may or may not load extensions for shell aliases
depending on whether the command is abbreviated or not.
Loading extensions may have useful side effects to shell aliases. For example,
the pager extension does not work for shell aliases.
This patch removes the code checking shell aliases before loading extensions
to give the user a more consistent experience. It may hurt performance for
shell aliases a bit without chg but the correctness seems worth it. It will
also make the behavior consistent with chg since chg will always load all
extensions before running commands.
