Before this patch, the shell alias causes failure when it takes its specific (= unknown for "hg") options in the command line, because "_parse()" can't accept them. This is the regression introduced by 7849ac1dbc57. It fixed the issue that ambiguity between shell aliases and commands defined by extensions was ignored. But it also caused that ambiguous shell alias is handled in "_parse()" even if it takes specific options in the command line. To avoid such failure, this patch checks shell alias again after loading extensions. All aliases and commands (including ones defined by extensions) are completely defined before the 2nd (= newly added in this patch) "_checkshellalias()" invocation, and "cmdutil.findcmd(strict=False)" can detect ambiguity between them correctly. For efficiency, this patch does: - omit the 2nd "_checkshellalias()" invocation if "[ui] strict= True" it causes "cmdutil.findcmd(strict=True)", of which result should be equal to one of the 1st invocation before adding aliases - avoid removing the 1st "_checkshellalias()" invocation it causes "cmdutil.findcmd(strict=True)" invocation preventing shell alias execution from loading extensions uselessly
